tsps baking soda<br />

Baking soda, chemically sodium bicarbonate (NaHCO₃), is a naturally occurring mineral salt that serves as a chemical leavening agent in baking. Mined from mineral deposits or produced synthetically through the Solvay process, baking soda is a fine, white crystalline powder with a slightly alkaline taste. When exposed to moisture and acid, or when heated, baking soda decomposes to produce carbon dioxide gas, which creates the rise in baked goods. Unlike baking powder, which is a complete leavening system, baking soda requires an acidic ingredient (such as buttermilk, lemon juice, or brown sugar) to activate its leavening properties.

Baking soda is essential in baking, primarily used to leaven quick breads, muffins, cookies, cakes, and pancakes when acidic ingredients are present. It is also employed as a tenderizer in marinades, a cleaning agent for cast iron cookware, and a deodorizer for baking vessels. Beyond baking, baking soda can be added to boiling water for pasta to enhance browning, sprinkled on chocolate chip cookies for chewy texture, or used to adjust the pH in batters. The key to its effective use is understanding its acidic counterpart: recipes typically call for one part baking soda per one part acid to achieve proper chemical balance and rise.
