First, mix the dough and knead the dough into a cylindrical shape. Then cut into small pieces of dough.
Take out a small dough, sprinkle flour on the small dough, and flatten the dough with your hands to make it as round as possible.
Pinch one end of the thick cake left and right, hold the rolling pin in your right hand, and start rolling the flat dough in one direction with the rolling pin. Just roll this little dough clockwise to the last place where it didn't roll.
In this way, the middle circle of the rolled dumpling skin is thin. If the middle is too thick or even bulging, you can gently press the bulging part down by hand. The making process of this dumpling wrapper is completed.
