Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Gelatin
Sets the coffee liquid into a firm, wobbly jelly when it cools.
Coffee
Provides the main flavor and liquid that becomes the jelly.
Sugar
Sweetens the coffee to balance its natural bitterness.

The step that matters

Dissolving the soaked gelatin in the hot coffee. Gelatin must fully dissolve in the hot liquid; undissolved granules leave gritty specks and weak spots. Straining after mixing helps catch any remaining lumps before the jelly sets.
