Baking soda is bicarbonate of soda, a top-quality leavening agent also known as sodium bicarbonate or sodium hydrogen carbonate. When used in combination with buttermilk, lemon juice, cocoa or other acidic ingredients, it causes dough and batters to rise beautifully without yeast! This pure baking soda is made from the deposits of mineralized sodium bicarbonate and is extracted by a simple water process that uses no chemicals.
When using baking soda in combination with acidic ingredients, such as buttermilk, molasses, cocoa or yogurt, the sodium bicarbonate releases carbon dioxide that causes the batter or dough to rise. In addition to carbon dioxide gas and bubbles, baking soda also yields a chewy texture that is essential to many baked goods—think of your favorite chocolate chip cookies. It’s also a great household cleanser and eliminates odors.
