Adding a certain proportion of starch to the batter will increase the crispy taste. If you prefer the feeling of swelling, you can also add a little baking powder, which is not added at home. If flour is used comprehensively, the taste may not be crisp. Practice: Mix flour and starch according to the ratio of 2: 1.

2. Add oil to the batter.

Mix flour and starch according to the ratio of 2: 1, then pour in proper amount of salt, edible oil and water and stir well. Cooking oil can also make batter crisp and fluffy. If you don't like baking powder, use cooking oil. Cooking oil alone cannot achieve the effect of baking powder.

3. The batter's state

When you pour the water into the batter, add it slowly, a little at a time and several times. The state should not be too thin or too thick, it is a relatively thick state that can flow. Take an eggplant for experiment and put it in the batter. The batter can be evenly wrapped on the surface of eggplant, and it is not easy to flow down.
