5 Tea Myths That Need to Disappear

5 Tea Myths That Need to Disappear

[Photographs: Vicky Wasik]
Maybe you started drinking tea for its purported health benefits, or as a less jittery alternative to coffee, or just because it tastes good. Whatever your reason, chances are you have some questions about it: how to brew it right, for starters, and what a really good cup should taste like. Fortunately there are many, many sources out there that simplify the vast world of tea into digestible nuggets of knowledge. Unfortunately, a lot of those sources—often the very companies selling you their tea—get some basic points pretty wrong.
Sometimes that bad advice comes from a well-meaning person who, in their efforts to make a complex topic easy to understand, oversimplifies to the point where they obscure the truth. Other self-identified experts are more dogmatic: there's only one right way to brew this tea, and if you disagree, you don't know what you're talking about.
The reality is that when it comes to tea, a crop grown all over the world in countless variations, boldly stated rules tend to fall apart when held up to closer scrutiny. Drinking tea seriously means learning with every pot you make, and considering its enormous complexity, there's rarely only one correct answer or right way of doing things.
So let's put those misleading rules to bed. I've tackled some of these topics in these teabasics stories, but here are five stubborn myths and misconceptions about tea that just refuse to die.

Myth #1: Black Tea Has More Caffeine Than Green

All tea has caffeine, usually less than coffee, though exactly how much varies from tea to tea, which leads some tea companies and pundits to break down caffeine content by broad style: green tea has this much caffeine, black tea that much, etc. They usually claim that black teas have more caffeine than oolongs, which in turn have more caffeine than greens and whites, though none of them agree on amounts. Depending on who you ask, a cup of black tea could have as little as 25 milligrams per cup or as much as 90. (Of course no one ever specifies the size of the cup.)
Broad generalizations like these make as much sense as saying all IPAs have the same alcohol percentage. All sorts of things influence a brewed tea's caffeine concentration, including where and how it's grown, the size of the finished leaves, and the exact processing style (roasting, aging, and fermentation can all diminish caffeine). A green tea may have as much caffeine as a black tea, and two black teas from the same region might have totally different caffeine levels.
It's even more complicated: The very same tea may yield different amounts of caffeine depending on how it's brewed. In a study in the Journal of Analytical Toxicology, researchers measured the caffeine content of 20 common tea products and found no correlation between tea style (green, black, etc.) and caffeine content. However, the longer any caffeinated tea brewed, the more caffeine made its way into the cup. Steep an English breakfast tea for one minute and you may get 14 milligrams of caffeine in your cup; steep the same amount for five minutes and that concentration can double.
Such evidence flies in the face of some tea sellers' claims that you can "decaffeinate" a tea by steeping it for 30 to 60 seconds, pouring out the brew, then steeping it again for a nearly caffeine-free cup. If you need to watch your caffeine consumption, stick to herbal tisanes, or try out roasted oolongs, aged teas, and "ripe" shou pu-erh styles, which many tea drinkers consider easier on the nerves. Or just steep your tea for shorter periods of time.

Myth #2: Boiling Water 'Burns' Delicate Teas

Conventional Western tea-brewing wisdom says black teas must be brewed with near-boiling water while delicate, prissy green and white teas need, nay, demand cooler water, usually around 160 to 175°F, lest you irreparably ruin their subtle flavors and transform their antioxidants into deadly neurotoxins.
In broad strokes, this isn't wrong. Black teas and darker oolongs do benefit from very hot water to extract the full range of their flavors with just the right dose of tannins, while many green teas will taste sweeter and less bitter with cooler water. But not every green or white tea is made the same way—as a category, green tea is as vast as white wine—and some greens and whites do just as well in fully boiled water as black teas.
Here's a good rule of thumb: the hotter you brew, the darker and more robust your tea will be; the cooler your water, the sweeter and more mild it'll taste. You can brew anytea with this in mind, see what tastes best to your palate, and adjust your brew parameters accordingly. A white tea or lightly oxidized oolong, for instance, will make two different brews at 175° and 205°. If it's a good tea, both brews should good; which you prefer is up to you. For what it's worth, I tend to start brewing a new tea with boiling water and dial it down from there if I need to. The same holds true if I'm brewing an herbal tea.
The big exception to this loosey goosey freedom is Japanese greens, which really do benefit from rigidity in brewing to achieve a balance in sweet and bitter flavors. Most, like sencha and matcha, do well in the 160° to 170° range, while shade-grown gyokuro benefits from even lower temperatures, around 140°. But no matter what you're brewing, it's your tea—don't rely on a label to tell to how to brew it.
If you do want to get super geeky about your brew temperatures, consider buying avariable temperature electric kettle with a full digital range so you can dial in any brewing temperature that your heart desires.

Myth #3: Black Teas Must Be Steeped Longer Than Greens

The same people who say you can never brew green tea with boiling water also tend to give timing guidelines on how long to brew your tea. Greens and whites, they say, should brew no longer than a minute or two, while blacks need a whole five minutes.
Such advice often doesn't take into account the size of the leaf (smaller, broken leaves brew faster than whole ones), the amount of water you use for a given quantity of tea (more water needs longer steeps), or what brewing that particular tea takes best to. A black tea bag in a mug, for example, only needs a minute or two to steep, while a 48-ounce pot of loose leaf English Breakfast will likely take longer. A Chinese dancong oolong, on the other hand, is best brewed with a ton of leaves in a tiny pot, with a series of flash steepings of just a few seconds each.
Your best practice? Taste as you go. Brewing tea is just a form of cooking, and like that roast in your oven, blindly following a clock rarely works out well. Want to get more technical? Take a look at these Chinese-style brewing suggestions that emphasize small pots, lots of leaves, and very short steeps (five to 30 seconds each). That's how I do it at home, and it's often the best way to taste everything your tea has to offer.

Myth #4: Organic Tea is Higher Quality

Demand for organic tea has skyrocketed over the past couple decades, and it shows no sign of stopping. In premium tea-growing regions like Darjeeling in India, plantation after plantation is going organic just to keep up with what the market. And as Jeff Koehler puts it in his new book, Darjeeling: A History of the World's Greatest Tea, the pressure to go organic is a boon for the region's soil, which after over a hundred years of intensive development and cultivation is eroding and depleting with every harvest.
But is government-certified organic tea always better for the environment? Nope. As with any produce, organic certification is just a label, and lots of large plantations are cashing in on organic caché while still engaging in unsustainable practices. Unfortunately Big Organic is just as prevalent in the Asian tea business as the California lettuce market. Meanwhile, many small farms that can't afford the organic certification process work in far more sustainable ways.
Even if a farm is 100% organic, its neighbors might not be, and if the farmer up the hill sprays his tea bushes, chances are those pesticides will make their way to the "unsprayed" organic crops through the air or groundwater. Meanwhile, a farm in total isolation might be using safe amounts of pesticides while providing a more healthy growing environment for its tea bushes.
Organic tea doesn't necessarily taste any better than conventionally grown tea, either. Up until relatively recently, many organic teas actually tasted worse than their conventional neighbors, as farmers were still negotiating the challenges of growing tea in an entirely different way. These days, though, the organic tea market is improving. But so are many parts of the conventionally grown tea market. If taste is your primary concern, don't think you need to pay a premium for organic leaves. And if you care about the environmental impact and health of your tea, there's a lot more to consider beyond an organic label. As always, buy from vendors you trust who in turn buy from farms they trust.

Myth #5: Green Tea is 'Better' for You Than Other Teas

We don't talk much about food and health on Serious Eats, and I don't plan to start now, but considering how many people start drinking tea for its purported health benefits, it's worth looking at green tea in some detail.
The most common claims in favor of drinking green tea are its low caffeine content and high antioxidant value. We've already dealt with the first claim—some green teas have just as much caffeine as other varieties. As for antioxidants, well, yes, thanks to its low oxidation, green tea possesses more antioxidants than black and oolongs. (Though lightly oxidized white teas often show even higher levels!) What those antioxidants do when you're drinking tea is far less clear, and there's far less scientific consensus on the practical benefits of regularly drinking green tea.
That's not to say there aren't any benefits, but rather that when sensationalist headlines call out green tea as a miracle cure for everything from allergies to cancer, it's worth taking a more skeptical perspective. It's also doubtful that green tea is the only kind of tea to make you feel good. Green tea's modern popularity means it dominates the scientific literature; researchers focus far less on certain dark, heavily processed teas that have been used as folk remedies for hundreds of years. Some tea drinkers consider roasted teas like dark tieguanyin to be more gentle on the stomach than bright greens, while others prefer the soothing sweetness of an inky-dark ripe pu-erh as a nightcap before going to sleep. Meanwhile, many tea drinkers report upset stomachs from drinking green tea without eating, a problem not shared by oolongs, black teas, and aged teas like pu-erhs.
As the Western world learns more about tea's hidden complexities, these myths should die out on their own. But for now, it's good to remember: no set of rules is a substitute for open minds willing to play with their food. Or their tea.

CURATA-TI SISTEMUL LIMFATIC IN DOAR 30 DE MINUTE! NU TE COSTA NIMIC!

Sedentarismul este unul dintre cele mai mari pericole la care suntem expusi in vremurile noastre si are la baza mai multi factori: tehnologia, stresul, locul de munca etc. Asa se face ca tot mai multi oameni ajung sa sufere din cauza unor boli generate de sedentarism si de blocarea circulatiei sanguine. Se naste astfel intrebarea: Care este cea mai buna tehnica de mers pe jos care optimizeaza drenajul limfatic si circulatia?

Sunt multe metode insa una dintre cele mai bune metode de a face acest lucru este extrem de usoara si nu te costa nimic – pur si simplu trebuie sa faci o plimbare in ritm alert timp de 20-30 de minute.

 “Dintre toate exercitiile, masaj, tratamente de detoxifiere si metode de vindecare, terapii New Age si tehnici integrative, nu exista niciuna mai eficienta si mai completa pentru curatarea sistemului limfatic ca o plimbare de 20-30 de minute in ritm alert(power walk) … mai ales daca este facuta in natura.”

Pentru ca sistemul limfatic nu are o pompa, fiecare persoana trebuie sa faca miscare regulat pentru a pune limfa in miscare. Asa cum sistemul circulator se bazeaza pe inima sa tina sangele in miscare permanent, sistemul limfatic se bazeaza pe miscarea corpului, si in special pe mersul pe jos.

In scolile ayurvedice de vindecare din estul Indiei se apreciaza ca practicarea zilnica a mersului pe jos zilnic este vitala. Se stie si ca niciun alt exercitiu nu pune in miscare limfa asa cum o face un mers alert de 20 – 30 de minute. Iar cand este facut in aerul curat al naturii, acest exercitiu are chiar si mai multe beneficii pentru sanatate.

Si un lucru mai putin cunoscut, cu cat locuiesti mai aproape de mare sau de munte, cu atat ai un aer mai incarcat cu ioni negativi. Astfel ca o plimbare pe malul marii sau o drumetie printre munti nu numai ca iti antreneaza gambele, te incarca si cu o doza buna de ioni negativi, spre deosebire de aerul imbacsit din orase si suburbii, deseori incarcat de ioni pozitivi.

“Cand mergi in pas alert(power walk), picioarele actioneaza ca o pompa naturala care pune limfa in miscare prin sistemul limfatic. Acest lucru este important pentru ca sistemul limfatic nu are o pompa asa cum sistemul circulator are inima ce pompeaza sangele. Este, deci, de inteles ca si partea superioara a corpului are nevoie de ajutor in acest sens.

Metoda cea mai eficienta de a practica mersul pe jos astfel incat acesta sa-si atinga scopul este sa-ti misti mainile la fel de viguros ca si picioarele. Exact, trebuie sa misti bratele ca un atlet de performanta – inainte si inapoi – in sus si in jos – intr-o parte si in alta – oricum ar fi, doar sa le misti. Acest lucru va avea efectul unei pompe pentru sistemul limfatic din partea superioara a corpului.”

Cultured Butter

Culturing The Cream

Cultured butter starts with cultured cream. The “culturing” results from leaving raw cream at left at room temperature to spontaneously sour as its own beneficial bacteria proliferate OR it results from the (raw or pasteurized) cream being innoculated with a culture. I’ve done it both ways — and both are delicious!
The spontaneous culturing can happen in an little as 24 hours at room temperature in a jar covered with a cloth. You can also then move the cream to cool storage to let the culturing mature, for several weeks even. Note: This does not work for pasteurized cream; there are not sufficient beneficial organisms to proliferate.
To innoculate cream, use about 1/8 teaspoon of a mesophilic culture per 1/2 gallon of cream. Stir in the culture, cover the jar with a cloth, and leave at room temperature for 24 hours. Then transfer to the refrigerator to chill, or to continue souring.
On Facebook, Julie from Cultures for Health added: “There are a couple of easy ways to culture cream. You can use a Buttermilk or Piima Yogurt as a starter culture (a tablespoon or two per pint of cream) or you can use a bit of mesophilic cheese culture like Wardee has done here.” Thanks, Julie! And Anne mentioned that kefir grains can be used to culture cream as well. Thanks, Anne!
The cream, no matter how it is cultured, must be chilled to make the butter. Or at least for the butter to appear any time soon.

What About The Taste?

Well, some do not like the taste of cultured butter so much. One person in my family likes sweet cream butter better. To each his own — but give me sweet and sour, deeper flavor butter any day! 😀 I suggest you try it and see whatyou think. No matter what, give yourself time to adjust to it. You will. I think you’ll learn to like it, if not love it.

In Pictures: Making Cultured Butter

This article at Mother Earth News is a great place to start for instructions. The following picture tutorial is based off those directions.
In the case of the butter below, I received a 1/2 gallon of cream which was already somewhat cultured. I let it sour more in the refrigerator for about 8 days until it was … perfect! Mmm… I can still taste it.
Take your chilled cultured cream and pour it into a mixer, food processor, or blender. Don’t use a Vita-Mix or the mixture will heat up. Whatever your container is, fill it it to less than half because the cream will expand during the churning. (Think whipped cream.)
I used a food processor with an 8-cup capacity. I added 3 cups of cultured cream at at time and process in batches until my quantity of cultured cream is turned into butter solids.
Pour the cream into the food processor bowl with the regular blade. Put on the lid and turn on. The process of churning may take between 5 and 10 minutes. The cream will go through stages on its way to butter. First, it will expand its volume and become whipped cream.

Then the butter solids will start to clump together and separate from the liquid (buttermilk). The whole mixture will appear grainy.


Then the solids will clump together even more until you have big chunks of butter floating in buttermilk. Churn just a minute or so more to complete the process of clumping the butter solids.

Transfer the butter solids to a bowl. The liquid is buttermilk and can be used in baking, smoothies, for soaking grains, you name it.

Repeat the churning process with all the cream until it is all collected in the bowl.

Now it is time to wash the butter. Add cold, clean water to the bowl and use a hard spoon, such as this bamboo spatula, to press and fold the butter into the sides of the bowl. The water will quickly turn clowdy as the remaining buttermilk releases from the butter solids.

Change the water repeatedly. Keep washing the butter until the water stays clear. When the water is clear, you have clean butter! The cleaner the butter, the longer it will last. The washing water isn’t true buttermilk as it is too watered down. It makes good water for animals or the compost.

Pour off the remaining water. Press and fold the butter a few more times to release any trapped water. Mix in sea salt, to taste. Then transfer the butter to some kind of mold, or you can just shape it into a log or chunks. I happen to have a butter mold, but only because it was given to me. 😀


Scrape off the mold.

Release the butter from the mold onto a sheet of natural wax paper.


This is a little bit of extra butter that didn’t fit the mold the first time.

Wrap up gently — the butter is still soft. I used natural wax paper for the wrapping. Transfer to the refrigerator to harden fully. Then wrap it more securely for refrigerator storage. It should keep for a couple weeks in the refrigerator, and perhaps more if washed well. Mine never lasts long enough to test how long it would last!
I hope you’ll give cultured butter a try. It is especially healthful when the cream comes from animals feasting on rapidly growing green grass. That butter is rich in fat-soluble vitamins.

All About Pancakes
Serious Eats digs into pancakes around the world.
I've been asked many times whether the material inmy book is 100% new, or whether it's just a collection of content from my existing articles. The answer is that it's a mix. Roughly 75% of it (and the pending follow-up book) is brand new material. Of the remaining 25%, at least another half is material that has been upgraded and tweaked since first publishing on the site.
I am a firm believer that any job in which you stop learning is not a job worth keeping. It's what's driven me through every career choice I've made, and what has kept me at Serious Eats for the last half decade. Not a day goes by here in which I don't learn something new about cooking, whether it's debunking a long-held belief, coming up with a new technique, or developing my skills in the classics.
Of course there's a corollary to this: The more you learn, the more you realize that your old work can do with some fine-tuning or upgrades. Long-time readers of The Food Lab may remember a pancake recipe I developed about five years ago. That recipe was good (good enough that it's one of my few perfect five-star-rated recipes), but it wasn't perfect. In fact, it's never gonna be perfect, but the more I learn, the better it'll get, and in the process of revisiting that recipe for my upcoming book, I ended up making a few changes, modifying the ratio of ingredients a touch, adding a step to get even lighter, fluffier results, and landing on an altogether better recipe that leads to better pancakes.
Here now, is the fully updated version as it appears in my book, along with plenty of science and an updated recipe. If you're itching for more, I'm afraid you're gonna have to wait until its September 21st release, but you can be the first kid on the block to get your copy by pre-ordering now either through Amazon or Barnes & Noble.

The Science of the Best Buttermilk Pancakes

They may be golden brown, crisp on the edges, and light and fluffy in the center, but when you get right down to it, classic American pancakes are not all that different from any leavened bread.
Apart from its starch content, bread is basically just a ball of protein filled with gas (very much like liquid, two proteins naturally present in wheat, glutenin and gliadin, link together to form the resilient, stretchy protein matrix known as gluten. In leavened breads, air bubbles are formed in this matrix and expand, creating the familiar hole structure inside a loaf of bread (or a good pizza crust, for that matter).
With traditional or "slow" breads, that leavening agent is a living fungus called yeast. As the yeast consumes sugars present in the flour, it releases carbon dioxide gas, forming thousands of teenytiny air pockets inside the dough and causing it to rise. Once you pop that dough into the oven, those air pockets heat up and further expand, and a phenomenon known as oven spring takes place. Finally, as the gluten and starches get hot enough, they set into a semisolid form, giving structure to the bread and turning it from wet and stretchy to dry and spongy.
The only problem with yeast? It takes a long, long time to work. Enter baking soda. Unrestricted by the protracted time frames of biological organisms, it relies instead on the quick chemical reaction between an acid and a base.
20150518-pancakes-new-kenji-07.jpg
Baking soda is pure sodium bicarbonate—an alkaline (aka basic) powder. When dissolved in liquid and combined with an acid, it rapidly reacts, breaking down into sodium, water, and carbon dioxide. Just as with yeasted breads, this carbon dioxide expands upon baking, leavening the gluten protein matrix. This type of chemically leavened bread is referred to as a quick bread, a broad category that includes everything from scones and biscuits to banana or zucchini bread and even pancakes.
Of course, for baking soda to work, a recipe needs to include a significant acidic ingredient. That's why you see so many classic recipes for buttermilk pancakes and buttermilk biscuits or cake recipes that contain vinegar. The buttermilk is not just a flavoring agent—it provides the necessary acid to react with the baking soda and leaven the bread. Around the middle of the nineteenth century, someone realized that rather than relying on the home cook to add an acidic ingredient to react with the baking soda, it'd be much simpler to add a powdered acid directly to the baking soda itself, and baking powder was born. Composed of baking soda, a powdered acid, and a starch (to absorb moisture and prevent the acid or base from reacting prematurely), baking powder was marketed as the all-in-one solution for busy housewives. In its dry state, it's totally inert. But once you add a liquid, the powdered acid and base dissolve and react with each other, creating bubbles of carbon dioxide, without the need for an external acid source.
Neat, right? But hold on—there's more.

Side Effects: The Maillard Reaction

The most interesting side effect of using baking soda in a recipe is that it affects browning in a major way. The Maillard reaction, named after Louise Camille Maillard, who first described its processes in the early twentieth century, is the set of reactions responsible for that beautiful brown crust on your steak and the deep color of a good loaf of bread. Aside from cosmetics, the reaction also produces hundreds of aromatic compounds that add an inimitable savoriness and complexity to foods.
As it turns out, the reaction occurs better in alkaline environments, which means that once you've added enough baking soda to neutralize the acid in a batter or dough, any extra you add will work to increase browning. So I made five batches of pancakes using identical batters consisting of flour, baking powder, egg, buttermilk, melted butter, salt, and sugar and varying amounts of baking soda, starting with none and increasing it by 1⁄8-teaspoon increments up to a full 1⁄2 teaspoon per batch. Each pancake was cooked on a preheated griddle for exactly 11⁄2 minutes per side. The results very clearly demonstrate the browning effect of baking soda.

20150518-pancakes-new-kenji-01.jpg
The pancake all the way on the left is inordinately acidic, due to the unneutralized buttermilk. It cooked up pale and bland. It was also underrisen, with a flat, dense texture. The one all the way around on the bottom, with a full 1⁄2 teaspoon of baking soda in the batter, had the opposite problem. It browned far too quickly, lending it an acrid burnt flavor tinged with the soapy chemical aftertaste of unneutralized baking soda. Interestingly enough, this pancake was also flat and dense—the large amount of baking soda reacted too violently when mixed into the batter. The carbon dioxide bubbles inflated too rapidly and, like an overfilled balloon, the pancake "popped," becoming dense and flaccid as it cooked.
This browning phenomenon isn't just limited to pancakes, of course. For example, cookie recipes routinely include baking soda to aid browning, even when there isn't an acid for it to react with.

Double Bubble

20150518-pancakes-new-kenji-02.jpg
If there's one major drawback with chemically leavened breads, it's that they need to be cooked pretty much immediately after the batter is mixed. Unlike a yeasted bread dough, which is low in moisture and kneaded until a tough, elastic gluten network forms to trap the massive amounts of carbon dioxide produced, a quick bread must be made with an extremely moist batter—baking powder simply doesn't produce enough gas to effectively leaven a thicker dough. Batters have relatively little gluten formation, meaning that they aren't all that great at trapping and holding bubbles. Once you mix a batter, your baking soda or baking powder immediately begins producing gas, and that gas almost immediately being trying to escape into the air. When working with quick breads, those who aren't into the whole brevity thing may run into difficulties.
Cook your pancakes immediately after mixing, and you get a light, tall, fluffy interior. Let the batter sit for half an hour, and you get a dense, gummy interior with few bubbles. But wait a minute, there are still some bubbles in there, right? Where did those come from?
20150518-pancakes-new-kenji-03.jpg
Well, pretty much all baking powder is what is referred to as "double-acting." Just as the name indicates, it produces gas in two distinct phases. The first occurs as soon as you mix it with water; the second occurs only when it is heated. This second rise in the skillet makes for extra-light and fluffy pancakes.

The Whites Are Light

So what if baking soda just isn't doing enough for you? How do you get your pancakes to stand even taller and lighter? I like to use a meringue—egg whites that have been whipped vigorously until they form a semisolid foam. Here's how it works:
  • Foam: In the early phases of beating, the proteins in the egg whites—mostly globulin and ovotransferrin—begin to unfold. Like nerds at a Star Wars convention, they tend to gather together and bond in small groups. The whites start to incorporate a few bubbles and resemble sea foam.
  • Soft peaks: As the whites are beaten, the groups of bonded egg proteins become more and more interconnected, eventually creating a continuous network of proteins that reinforce the walls of the bubbles you're creating. The whites begin to form soft peaks.
  • Stiff peaks: As you continue to beat, the reinforced bubbles are broken into smaller and smaller bubbles, becoming so small that they are nearly invisible to the naked eye and thus the whites appear smooth and white, like shaving cream. When pulled into peaks, they remain stiff and solid.
  • Breakdown and weeping: Keep going past the stiff-peak stage, and the proteins begin to bond so tightly with each other that they squeeze the moisture right out of the bubbles, resulting in a meringue that weeps and breaks. Acidic ingredients like cream of tartar or a touch of lemon juice can prevent egg white proteins from bonding too tightly, allowing you to form a foam that stays stable no matter how hard you beat it.
 Add sugar and vanilla to the whites at the soft-peak stage, whip to stiff peaks, drop by the spoonful onto baking sheets, and bake at a low temperature, and you've got yourself classic meringue cookies. If you instead drizzle in a cooked sugar syrup toward the end of whipping, you'll end up with what's called an Italian meringue, a meringue that stays soft and supple even when browned—the kind of thing you'd want to top a lemon meringue pie with.
20150518-pancakes-new-kenji-05.jpg
Here the use for meringue is much more simple: all you're going to do is fold it into the pancake batter. The extra air that the egg whites have incorporated expands as the pancakes cook, making them featherlight.
20150518-pancakes-new-kenji-06.jpg

Pancake Flavor

20150518-pancakes-new-kenji-08.jpg
As far as flavoring buttermilk pancakes go, there are a few givens: Dairy fat, in the form of melted butter or milk, is essential. Not only does it add richness and flavor to the mix, but by coating the flour and limiting gluten development, it also ensures that your pancakes remain tender. Eggs help set the pancakes as they cook, as well as providing some extra lift. Buttermilk is obviously part of the equation, but I like my pancakes extra-tangy, and straight-up buttermilk just doesn't cut it for me. Increasing the quantity doesn't work—that just ends up throwing the liquid-to-solid ratio out of whack. Instead, I replace part of the buttermilk with a good amount of sour cream. It's both less moist than buttermilk and more sour, which allows me to add acidity without watering down the batter. If you don't have sour cream on hand, don't worry—the pancakes will still taste just fine with straight-up buttermilk.

EXPERIMENT: Double-Acting Baking Powder

Double-acting baking powder (the type sold in any supermarket) is designed to produce bubbles in two distinct phases: when it gets wet and then when it gets heated. You can see this for yourself.
Materials:
  • 1 teaspoon baking powder
  • 1 tablespoon water
  • Procedure:
  1. Combine the baking powder and water in a small bowl. You'll notice that the baking powder imme- diately starts bubbling and fizzing (if it doesn't, throw out your baking powder and buy a new can). This is the first reaction. After 30 seconds or so, all action will cease, and you'll end up with a still pool of chalky-looking liquid.
  2. Now microwave that liquid for about 15 seconds to bring it up to 180°F. A second, vigorous batch of bubbling should occur. You may also notice the liquid thicken slightly.
Results and Analysis:
When the baking powder first gets wet, a reaction occurs between the sodium bicarbonate and one of the powdered acids, typically potassium bitartrate (aka cream of tartar), producing the first batch of bubbles. The second phase of the double act occurs only at higher temperatures (around 170° to 180°F), when a second powdered acid (typically sodium aluminum sulfate) reacts with the remaining sodium bicarbonate, producing another round of bubbles. The thickening action is a side effect of the starch used to keep the baking powder dry--it absorbs water and gelatinizes, thickening your liquid as it heats. Now isn't that way cooler than that baking soda volcano you built for your fourth-grade science fair?

What is Buttermilk?

True buttermilk is the liquid whey left after cream has been churned to create butter. Traditionally this whey was allowed to ferment into a slightly thickened, sour liquid that would keep longer than fresh milk. These days, though, buttermilk is made from regular milk by dosing it with Streptococcus lactis, a bacteria that consumes lactose, the main sugar in milk, and produces lactic acid, which adds tartness to the buttermilk, as well as causing casein, the primary protein in milk, to curdle, thickening, or clabbering, the milk.
In some recipes, it's possible to substitute artificially clabbered milk--milk to which an acid like vineger or lemon juice has been added to thicken it--for buttermilk, but you'll always be left with a telltale flavor from the added acid. Much better is to substitute another soured dairy product. When I have no buttermilk on hand, I'll use yogurt, sour cream, or even crème fraîche diluted with milk.

Substituting Baking Soda for Baking Powder

Baking soda is sodium bicarbonate. It reacts with liquid acids immediately upon contact to produce carbon dioxide. Carbon dioxide gets trapped within batters and expands upon baking, leavening your pancakes and other quick breads. Because baking soda reacts immediately, quick breads made with it must be baked or cooked right after mixing. And because of its alkalinity, baking soda can also hasten browning reactions, adding color (and thus flavor) to things like pancakes, cookies, and muffins.

Baking powder is sodium bicarbonate mixed with one or more of the powdered acids and a starch. It does not require another acid to activate it. As mentioned earlier, most baking powders are "double-acting," meaning they produce carbon dioxide once upon coming in contact with moisture and then again when heated. Because of this, baking powder-leavened goods are generally lighter and fluffier than those made with baking soda alone. This doesn't mean, however, that you can let a baking powder batter just sit around, expecting the second batch of bubbles to do all the leavening--the initial reaction is vitally important to the texture of your baked goods, and so these batters should be baked right away too.
Don't have baking powder on hand? It's quite simple to substitute with your own homemade mixture of baking soda, cornstarch, and cream of tartar. For every teaspoon of baking powder, use 1⁄4 teaspoon baking soda, 1⁄2 teaspoon cream of tartar, and 1⁄4 teaspoon cornstarch. But do bear in mind that your homemade mixture will not be double-acting, requiring you to be extra quick about getting your pancakes onto the griddle or your zucchini bread in the oven after mixing the batter.
