How to make cold noodles:

1. Add appropriate amount of high-gluten flour and water to form a dough. 2. Then put the mixed dough into clean water and rinse it repeatedly to wash out the starch in the flour until gluten appears. 3. Put the washed flour water into the refrigerator. I usually leave it overnight. Anyway, the longer the better. 4. The next day, take out the precipitated starch water and pour out the clear water on top, leaving a starch lake. Thin silk can be mastered by yourself. 5. Boil water, put the cage in place, put a small tray, apply a little cooking oil on the tray, then pour 2-3 mm of starch lake, steam over high heat for 5 minutes. If you want it thicker, you can make it yourself, but it tastes better if the skin is thinner. 6. Put the steamed skin into cold water, gently peel it off with your hands, and put it on a plate. An appropriate amount of cooking oil should be applied in the middle of each layer of cold skin, firstly to prevent adhesion, and secondly to make the color look good.
