Gelatine, also known as fish film, must be soaked in cold water to soften or "absorb water" before use. Dissolved gelatine can only be mixed with other mixtures after cooling; Otherwise, it will become one by one. The dissolution ratio is 1 teaspoon of gelatin 1 tablespoon of water.

1. Pour water into a heat-resistant bowl, sprinkle with gelatin and let it "absorb water" for 5 minutes. 2. Put the bowl in the pot and heat it in water until the gelatin is clear and transparent. Cool before use.
