When excessive acidity is present, some of the baking powder is replaced with baking soda.

Substituting in recipes

Baking powder is generally just baking soda mixed with an acid, and a number of kitchen acids may be mixed with baking soda to simulate commercial blends of baking powder. The most common suggestion is to use two parts cream of tartar with one part baking soda. Vinegar (dilute acetic acid), especially white vinegar, is also a common acidifier in baking; for example many heirloom chocolate cake recipes call for a tablespoon or two of vinegar. Where a recipe already uses buttermilk or yoghurt, baking soda can be used without cream of tartar (or with less). Alternatively, lemon juice can be substituted for some of the liquid in the recipe, to provide the required acidity to activate the baking soda. Sodium bicarbonate (NaHCO3), or sodium hydrogen carbonate, also known as baking soda and bicarbonate of soda, is a soluble white anhydrous or crystalline compound, with a slight alkaline taste resembling that of sodium carbonate. ... Cream of tartar is the potassium salt of tartaric acid, KHC4H4O6. ... Vinegar is sometimes infused with spices or herbs—as here, with oregano. ...
