How to make the fried batter crispy?

The recipe of fluffy crispy batter is as follows:

1, adding baking powder and edible oil.

When making crispy paste, baking powder and cooking oil must be added, because baking powder will produce a lot of carbon dioxide gas after heating, carbon dioxide can make crispy paste more fluffy, thus making fried food more crisp, while cooking oil can reduce the toughness and elasticity of crispy paste, thus making fried food more crisp.

2. The ratio of flour to starch is 3 1.

When making crispy paste, we must strictly grasp the proportion of flour and starch. To make the finished product crisp, the ratio of flour to starch must be 3: 1. If there is too little flour, the finished product will not taste good. If there is more flour, the finished product will not be brittle.

3. Don't add protein

Many families don't have custard powder, so in order to make fried food look more golden, they put 1 egg in it. In fact, when making crispy paste, egg whites and egg yolks are the most taboo, but with custard powder, you don't have to put them.

Matters needing attention in making crispy sauce:

1, the ratio of flour to starch is 1: 2, remember to add baking powder, which will make the fried batter more fluffy.

2, there is no need to add eggs, which will not cause fried food to soften quickly.

3. When mixing the crisp paste, follow the principle of adding a small amount of water many times to avoid adding more water. I don't know how to adjust the proportion of other ingredients later.
