Wheat starch is extracted from wheat. In the past, it was fermented, that is, wheat was softened by adding water, ground, and then fermented by adding acid, so that the cells surrounding starch particles were dissolved and the starch was easy to separate. It can make delicious food:

1, cold rice noodles:

Add water to the flour, make the flour into dough, knead the flour repeatedly in the water, pour out the flour, and repeat for more than four times.

Let the noodle water stand for two hours, then pour off the clear water.

Stir the batter evenly, spread it out on a plate and steam it.

2, the practice of purple sweet potato heart meatballs:

Cut the purple sweet potato, steam and crush it, then add two tablespoons of glutinous rice flour and wheat starch into the purple sweet potato paste and knead it into a dough with moderate hardness.

Knead into purple potato balls and fry them in oil pan until the balls swell a little.
