You have to make a dough first, preferably high-gluten flour, and add some salt to ordinary flour, which is the same. You can wake up for half an hour after makeup, and then you can start washing your face with a bigger basin and add some water, just like washing clothes, until you can't wash white flour water anymore. What's left is gluten. You should add some yeast to the gluten, wake it up for a while, and then steam it in the pot! However, only big dough can wash out a little gluten! Don't pour the water on your face, put it in the refrigerator for 6-8 hours, pour off the top water, stir the rest evenly and put it in a transparent pot. Use a thin stainless steel plate, pour a thin layer on it, put it in the pot for 30 seconds, take it out, rinse it with cold water, and you can take it out. In this case, gluten and cold noodles are ready! Hehe, I wish you success! ! !
