How to Make a Basic Gelatine Mixture
This simple procedure–combining unflavored gelatine with a liquid–is the basis of all gelatine dishes. (When recipe calls for 1 tablespoon gelatine use 1 envelope.)
*If the recipe calls for 1 tbsp. or more of sugar, it is not necessary to soften the gelatine in the liquid. Just mix the gelatine with the sugar and add the liquid.
