There are two reasons why the dumpling skin is hard:
1, moisture: If the dumpling skin is hard, it may be caused by water loss, because the dumpling skin itself is relatively thin, and the area is relatively large, which is easy to cause moisture, resulting in a hard dough.
2. Flour: The choice of flour may also affect the hardness of dumpling skin. Generally, dumpling wrappers are made of medium gluten flour. The dough made of medium gluten flour has moderate softness, high gluten flour has strong toughness, and low gluten flour is easy to break.
