According to the query of Gourmet World and Good Looking Video, it is known that the process of making the filling of the Su-style mooncake usually does not require the addition of water, but rather the use of oil, sugar, honey, etc., to flavor and increase the moistness of the filling. If water is added, it may cause the filling to be too moist, affecting the flavor and preservation of the mooncake. The essence of the Soviet-style mooncake is the crispy skin, and the crispy skin mainly comes from the extreme production of the water-oil skin, and in the production process of the oil skin, because there is no need to add water, so the excessive kneading of the grease is gradually hardened, losing the soft texture. Therefore, the skin crispy or not is also related to the force.
