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

What each ingredient does

Gelatine
Sets the coffee liquid into a wobbly, firm jelly as it cools.
Strong hot coffee
Provides the main flavour and liquid that becomes the jelly.
Sugar
Sweetens the coffee and balances its bitterness.
Rich whipped cream
Adds richness and a cool, fatty contrast to the bitter coffee jelly.

The step that matters

Soak the gelatine fully before adding hot coffee. Gelatine must hydrate in cold water first so it dissolves evenly in the hot liquid. Skipping or shortening the soak can leave lumps or weak setting.
