What each ingredient does

Gelatine
Sets the liquid into a wobbly jelly as it cools.
Strong black coffee
Provides the main flavour and dark colour of the jelly.
Sugar
Adds sweetness that balances the bitterness of the coffee.
Boiling water
Dilutes the coffee and helps dissolve the gelatine and sugar.

The step that matters

Dissolving the gelatine fully. Gelatine must be completely dissolved in the hot liquid before chilling. Any undissolved granules will leave specks and an uneven, weak set, so stir until no grains remain.
