HOW TO DISSOLVE GELATINE
DISSOLVING GELATINE…Sprinkle gelatine evenly over cold liquid; do not pour in a heap. Stir constantly over low heat until dissolved…about 2 or 3 minutes. Use a medium saucepan, about 2 quarts, rather than a small one. This provides more surface area and the gelatine dissolves more quickly.
GELATINE IS DISSOLVED…when there are no visible granules in the liquid. Only if gelatine has been completely dissolved will the mold be firm.
