Baking powder contains both an acid and a base in dry powdered form, and simply needs a liquid medium in which to react. [5] Other alternative leavening agents are egg whites mechanically beaten to form stiff peaks, as in the case of many waffle recipes, or steam, in the case of cream puffs.
Disodium pyrophosphate is a popular leavening agent found in baking powders. It combines with sodium bicarbonate to release carbon dioxide: Na 2 H 2 P 2 O 7 + NaHCO 3 → Na 3 HP 2 O 7 + CO 2 + H 2 O. It is available in a variety of grades that affect the speed of its action.
They are leavened primarily by the air that is beaten into the egg whites that they contain. [1] They differ from butter cakes, which contain shortening, and baking powder or baking soda for leavening purposes. Foam cakes are typically airy, light and spongy. [1]
The breakthrough in chemical leavening agents occurred in the 1930s with the introduction of monocalcium phosphates (Ca(H 2 PO 4) 2). Other leavening agents developed include sodium aluminium sulfate (NaAl(SO 4) 2 ·12H 2 O), disodium pyrophosphate (Na 2 H 2 P 2 O 7), and sodium aluminium phosphates (NaH 14 Al 3 (PO 4) 8 ·4H 2 O and Na 3 H 15 ...

To make a poached egg in the microwave, crack one egg in a mug and add 1/3 cup of water. Cover it with a dish, and set the microwave for 50 seconds on high. Cover it with a dish, and set the ...
Macaroons became a popular treat for Jews on Passover because they had no flour or leavening as macaroons are leavened by egg whites. [7] [8] Recipes for macaroons appeared in recipe books at least as early as 1725 (Robert Smith's Court Cookery, or the Complete English Cook), and use egg whites and almond paste. [6]
As cream of tartar is added, the pH decreases to around the isoelectric point of the foaming proteins in egg whites. Foaming properties of egg whites are optimal at this pH due to increased protein-protein interactions. [17] The low pH also results in a whiter crumb in cakes due to flour pigments that respond to these pH changes. [16] However ...
