Cake classification:
Cakes can be generally divided into three categories according to their raw materials, blending methods and batter properties.
1. Pasta cake: The amount of grease in the formula is as high as about 60% of the flour, which is used to lubricate the batter to produce soft tissues and help the batter to mix a lot of air during the mixing process to produce bulking effect. Generally, cream cakes and pudding cakes belong to this category.
(2) Milk foam cake: The formula is characterized in that the main raw material is eggs without any solid fat. Protein, which is tough and denatured in egg liquid, is used to make the cake puffy during the process of batter mixing and baking. According to the egg materials used, it can be divided into protein (such as angel cake) and sponge (such as sponge cake) using whole eggs.
(3) Qifeng Cake: It is made by mixing batter and foam, and changing the organization of foam cake.
