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

What each ingredient does

Gelatine
Sets the liquid into a firm, wobbly structure as it cools.
Milk
Adds creaminess and body, softening the coffee's bitterness and giving a smooth texture.
Sugar
Sweetens the dessert and adds body to the set mixture.
Coffee
Provides the main flavour and aroma of the dessert.

The step that matters

Add the soaked gelatine and stir until melted. Gelatine must be fully dissolved in warm liquid before setting; undissolved granules leave grainy, weak spots in the final set. Stirring until no granules remain ensures an even, smooth gel.
