According to the inquiry of delicious food videos, in the process of making Su-style moon cake stuffing, it is generally not necessary to add water, but to season with oil, sugar and honey to increase the wettability of the stuffing. If water is added, the filling may be too wet, which will affect the taste and preservation of moon cakes. The essence of Su-style moon cakes is crispy skin, which mainly comes from the perfection of making water-oil skin. In the process of making oil skin, because there is no need to add water, excessive kneading will make the oil gradually harden and lose its soft taste. Therefore, whether the skin is crisp or not is also related to strength.
