Can beer or pop be the only leavener in a cake?
In recipes, I've seen beer and pop as a leavener along with some small amount of baking soda. Is there enough carbonation in beer or pop alone to leaven a cake?
Most of the recipes I've seen that use beer or carbonated beverages as an ingredient rely on boxed cake mixes which already have leavening agents in them. But beer and carbonated beverages can act, exclusively, as a leavening agent with a small amount of baking soda (sometimes with a small amount of baking powder) and it is not uncommon for those ingredients to be used in pancake batters. Batters for tempura are often made using beer as the sole leavening agent.
