About baking soda
Baking soda is a naturally occurring mineral compound, sodium bicarbonate, often mined from trona deposits or produced synthetically. It has a fine, white crystalline texture and neutral smell. In cooking and baking, it acts as a chemical leavening agent that produces carbon dioxide gas when combined with acidic ingredients like buttermilk or lemon juice, causing batters and doughs to rise and creating a light, airy crumb structure.
