2, with 25 grams of starch + 50 grams of flour + 2 egg whites to hang the paste can be hung on the surface of the fish 1-2 millimeters appropriate (you can add the right amount of water)
3, deep-fried fish in two steps: the first frying in high oil temperature (also known as the tight skin), the pan and let it sit for a while after the frying in oil temperature
The above is my personal customary practice, you can try it is quite delicious
This is a good idea to try a little bit more, but I'm not sure if you can do it, because I don't think you can do it.
