A process of making gelatin desserts includes adding gelatin powder to a vessel; adding water, sweetener, and food coloring to the vessel to form a gelatin solution in the vessel; mixing and heating the solution to a temperature of 85-90° C.; adding acid to the solution; adding essence to the solution; homogenizing the solution to keep the solution at a pH value of 3.5 to 3.9; adding alcohol to the homogenized solution; keeping the homogenized solution at a temperature of 65 to 79° C.; pouring the homogenized solution to a container out of the vessel; sealing the container; heating the sealed container for 12-15 minutes until the sealed container is kept at a temperature of 65-79° C.; cooling the sealed container to form a gelled gelatin half-finished product having an alcoholic flavor; and packaging the gelled gelatin half-finished product into gelatin desserts.
