What each ingredient does

Gelatine
Sets the liquid coffee into a firm, wobbly jelly as it cools.
Coffee
Provides the main flavour and liquid base of the jelly.
Sugar
Sweetens the coffee and helps it dissolve evenly into the liquid.

The step that matters

Soak the gelatine until soft. Gelatine must hydrate fully in cold water before it is added to the hot coffee, otherwise it clumps and sets unevenly, leaving a grainy or lumpy jelly.
