One: pasta suitable for making with hot water dough;

Hot water dough is also called boiling water dough or hot noodles. The water temperature of the dough is generally 60- 100 degrees.

Under the action of hot water, protein in flour coagulates and decomposes water, so gluten is destroyed, and starch absorbs a lot of water and expands into paste and decomposes monosaccharide and disaccharide. Therefore, the hot water dough is waxy and weak, and the finished product is translucent, with poor color, but it is delicate, sweet and easy to mature when heated.

Hot water noodles are suitable for making steamed buns, steamed dumplings, steamed dumplings, pot stickers and oil cakes.

Warm water and dough are characterized by softness, strength, plasticity and easy forming;

It is not easy to lose its shape after cooking, and it has moderate taste and white color. This feature is especially suitable for making steamed cakes with various colors, such as cabbage cakes, goldfish cakes and four-wedding cakes.

Cold water dough is a kind of water-mixed dough mixed with water at a temperature below 30 degrees, commonly known as cold water surface.

Because the flour is mixed with cold water or low temperature water, the protein in the flour cannot undergo thermal denaturation, thus forming more and stronger gluten.

Starch does not swell and gelatinize at low temperature, so the dough formed is firm, tough, tensile and stiff, also known as "dead noodles".

The characteristics of cold water surface are that the finished product is white in color, refreshing and chewy, and not easy to break. It is generally suitable for boiled and baked varieties, such as dumplings, noodles, spring rolls, pearl soup, pancakes and so on.

Therefore, the skin of spring cakes should be cooked with cold water.

I hope my answer can help you.
