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 firm, wobbly jelly when chilled.
Boiling coffee
Provides the liquid base and the coffee flavour of the jelly.
Sugar
Sweetens the coffee so it balances its bitterness.
Whipped cream
Adds a rich, fat-based contrast to the cold, lightly firm coffee jelly.

The step that matters

Soak the gelatine before adding the hot coffee. Gelatine must hydrate in cold water first so its protein strands spread evenly; added straight to hot liquid it can clump and set unevenly.
