What can be used as a substitute for raising agents?

Substitutes for raising agents include baking soda combined with an acid like vinegar or lemon juice, which creates carbon dioxide to help dough rise. Yogurt or buttermilk can also be used with baking soda, while whipped egg whites can provide lift in recipes such as soufflés and meringues. Additionally, self-rising flour, which contains baking powder, can replace all-purpose flour in some recipes.
