Chengfen can be replaced by raw flour. However, the dim sum made of cornstarch will be translucent. If cornstarch is used instead of cornstarch, the effect is not so obvious.

If there is no starch to make, soften the wheat flour into dough and wash it directly in water. When the volume of the dough is no longer reduced after washing, the remaining dough is gluten, and the starch is in the water. Just let the water stand properly until it is clear and turbid, then slowly pour out the upper water, and the remaining sticky matter will be dried or dried to get starch.

Precautions:

Wash the wheat flour and dough directly in water until the volume of the dough is no longer reduced, and the remaining dough is gluten, and the starch is in the water. Let it stand and precipitate. When the turbidity is separated, you can reflect the figure and slowly pour out the water on the upper layer. The sticky substance below is dried or dried to become starch.

When the flour is used, it is brewed with boiling water to make it gelatinized and sticky, and then it can be used as dough. The gelatinized starch can also be used as an adhesive, which is natural and environmentally friendly and sticks firmly, but it is easy to get moldy in high temperature and high humidity environment.

Using potatoes or sweet potatoes to make pulp, or using mung bean flour to make dough, you can also make corresponding flour, but it is difficult to get gluten.
