The specific methods of homemade noodles are as follows:
1. Put warm water in a fresh-keeping box, add dry yeast and mix well, then add high-gluten flour and salt and mix well;
2. Cover, ferment at room temperature for 2 times, and then ferment in the refrigerator for 24 hours. When you open the dough with your fingers, you will find many honeycomb-like pores, and no sour taste is the best state;
3. The prepared old noodles can be stored in the refrigerator for about 3 to 4 days, or they can be stored in the refrigerator for one month. Take it out and heat it before use, and mix it into the main dough for later use. Add new ingredients to the rest to make old noodles, and repeat them every time.
