In culinary applications, sodium bicarbonate is most notably used as a leavening agent. It reacts with acidic ingredients—such as buttermilk, vinegar, or yogurt—to release carbon dioxide gas. This process causes dough and batter to rise, creating a light and fluffy texture in baked goods. For instance, cookies, cakes, and muffins often rely on baking soda to achieve their desired consistency. However, it’s important to measure it carefully, as too much sodium bicarbonate can lead to an unpleasant, soapy taste.
