It also helps strengthen the structure of egg whites so they don’t deflate so quickly which is very handy when making meringues. In fact, it’s one of the powdery acids used in baking powder to help leaven products. That substance is harvested and purified and sold as cream of tartar. After wine has been fermented and aged in barrels, it leaves behind a powdery substance. So, what is it? It’s actually a byproduct of wine production. It’s not a cream, not does it bear any relation to the tartar one hears about during dental visits. For every 1 teaspoon of baking powder, substitute: 1/4 teaspoon baking soda, 1/2 teaspoon cream of tartar, and 1/4 teaspoon cornstarch OR 1/4 teaspoon baking soda plus 1/2 cup buttermilk, sour milk or yogurt (for this substitution, you’ll want to decrease the liquid in the recipe by half) Contamination happens when the same measuring spoon is used to measure other ingredients before it’s used to measure the baking powder.ĭon’t have baking powder? You can make your own. If the baking powder doesn’t fizz when wet, it’s no longer active and should be thrown out.Īlso, like baking soda, baking powder is usually dated with a “best by” range of 18 to 24 months, but it will last indefinitely if it does not become contaminated. Put one teaspoon of baking powder in a small bowl and mix in one tablespoon of warm water. Like baking soda, you can test it to see if it’s still effective. Most baking powders are commonly double-acting. Your recipe will specifically call for single-acting baking powder if needed. There are single-acting baking powders available these powders only rise once during the heating stage of baking. This two phase rising method is known as double-acting. The second rising phase happens when the other powdery acid reacts with the remaining baking soda producing more bubbles when exposed to heat over 170☏. First, the baking soda in the powder along with one of the acids starts producing carbon dioxide bubbles when they’re mixed with wet ingredients. Like baking soda, it makes products rise by producing carbon dioxide gas however, it does so in two phases. It’s usually found in recipes that do not call for additional acids because it already contains acid. This ingredient is a mixture of baking soda and powdered acids. Vigorous mixing will cause bubbles to break. Protecting those bubbles is also why you’ll want to mix batters lightly. It’s better to use it right away (or at least within the hour) especially once the baking soda and acidic ingredient has been combined. So, it’s probably not a good idea to make and hold a batter for a long time. Keep in mind, baking soda becomes reactive when it’s exposed to acids (buttermilk, vinegar) and must be used right away otherwise the carbon dioxide-producing bubbles will begin to pop and result in a flat and dense product rather than something light and airy. Now, this is a great use for baking soda, but just don’t use that baking soda for baking and cooking anything.īaking soda is often labeled with a best by date of 18 to 24 months, but you can always test its effectivity by mixing 1 1/2 teaspoons of baking soda in a bowl with 1 tablespoon of vinegar. In fact, baking soda used for cooking shouldn’t be kept it in the refrigerator because it will absorb orders lingering in that environment. But both cause products to rise by producing carbon dioxide gas, just in different ways.Īnd because baking soda is not a living organism, it’s pretty shelf stable for quite some time. This technique is different than using yeast to leaven bread because yeast is a biological process since it’s a living organism that produces the carbon dioxide gas from eating various carbohydrates found in the batter. On the other hand, if you have dense rocks for pancakes, then your baking soda might not be working. Combining baking soda with an acid produces a chemical reaction that releases carbon dioxide gas which causes the food to expand and become fluffy. It’s used to chemically leaven doughs and batters when it is mixed with an acid. So what are they?Ĭhemically known as sodium bicarbonate, baking soda is a type of salt that’s made by mixing carbon, sodium, hydrogen and oxygen molecules. Yes, baking soda is IN baking powder, but they are not interchangeable items. The first thing you should understand about baking soda and baking powder is that they are NOT the same thing. This led me to ponder about certain ingredients that are the key leavening agents used in baked goods baking soda, baking powder and cream of tartar. Even myself, who admittedly is not a skilled baker, will trifle through the dessert sections of cookbooks looking for something scrumptiously sweet and oven-baked.
