1. Take a piece of dry gluten to be soaked, and soak it as much as you eat. It is not good to save it after soaking.

2. Take a pot a little bigger than gluten, because gluten is hard and easy to break into slag. Borrow hot water or warm water from the basin.

3. Put the gluten in a pot and soak for about 4 minutes.

after 4 or 4 minutes, knead the gluten for hard pimples, mainly touching the surface of the gluten, where it is not easy to foam, otherwise it means it has been foamed.
