Features: Ammonia powder is one of the chemical leavening agents. It has a very pungent odor, which produces gas when heated to achieve expansion.
Generally used in deep-fried products and cakes that need bulkiness. Usually used to make puffs or You Tiao. To make pastry and other pastry desserts, adding some stinky powder in an appropriate amount can make the peach pastry surface naturally cracked.
You can barely use baking powder or baking soda, but the expansion and cracking effect is not so good.
