Egg white introduction:
Egg white is a transparent colloidal substance wrapped around the yolk, which is composed of protein. So it is also called protein, as opposed to egg yolk. Protein will solidify into a white solid when heated, hence its name. Protein is as shockproof, moisturizing and protective as mammalian amniotic fluid. If you mix the egg whites with a high-speed whisk, they will be as elastic as a sponge, which is the first step in making a cake.
Egg white paste, also known as protein paste, has a thick and thin surface, about 1.5 mm, and a soft texture. The raw material for making egg white paste is egg white with dry starch or refined white flour, and the ratio of egg white to flour is about 1: 1.
