1, double-effect baking powder should be melted in hot water for use. Double-effect baking powder is a kind of baking powder, which is generally made of acidic bulking agents such as calcium hydrogen phosphate and potassium hydrogen tartrate. It has a double-rising effect and can rise when heated and dissolved in water.

2. Before using the double-effect baking powder, put the required flour into the basin and prepare the double-effect baking powder according to 2-3% of the flour. After adding it, add an appropriate amount of water, stir it evenly, knead it into a suitable dough by hand, and let it stand for a while.

3, about 1 hour or so, there will be many small pores on the dough, which is a good phenomenon of dough fermentation. However, the fermentation time of dough depends on the temperature, so the time cannot be generalized.

4. Double-effect baking powder will react when exposed to heat or water, so it is better to melt the double-effect baking powder with hot water, which can promote fermentation. Double-effect baking powder is mainly used to make pastry, and its usage is not very troublesome. Just add it to flour and then add a proper amount of warm water.

5, dough fermentation is indispensable for double-effect baking powder, of course, it can also be replaced by baking soda. When baking powder is used to ferment dough, pastry will rise quickly, which will save more time and make the food taste better. However, it is necessary to pay attention to proper addition, not too much.
