2. Before starting production, we must first determine the required amount of paste and determine the amount of raw materials according to the demand. Generally speaking, the volume ratio of starch to water is about 1:3, that is,100g of starch should be diluted with 300g of water.
3. After determining the dosage, put the starch into a bowl, pour water in proportion, and slowly stir in one direction with chopsticks to fully dissolve the starch in cold water.
4. Then pour the stirred starch solution into the pot, turn on a small fire and keep stirring with a shovel. Remember to turn on a small fire and keep stirring, so as not to burn the solution. Dissolved starch will evaporate with water, and the consistency of flour will become more and more sticky until it is cooked into a paste.
It is very firm to stick couplets with this glue, and the traces of the glue are well removed. Just wipe it off with a towel after getting wet, and don't worry about leaving traces!
When flour or starch is boiled into paste with water, it is paste (Modern Chinese Dictionary, 6th Edition, the Commercial Press uses "paste"). Paste has a certain viscosity, and is mostly used to bond paper, cloth or articles. Modern production is mostly chemical paste made of cellulose and glue. Using wheat starch as raw material, the consistency of the paste is starch ∶ water = 1 ∶ 6, the properties of the paste are relatively stable, and the cooking temperature is better than 80℃.
