What each ingredient does

Gelatin
Forms the firm, wobbly set that holds the jelly's shape when chilled.
Dry coffee
Provides the main coffee flavor and its slightly bitter aroma.
Sugar
Adds sweetness that balances the bitterness of the coffee.

The step that matters

Dissolve the gelatin in the hot coffee mixture. Gelatin must dissolve completely into the warm liquid so it sets evenly. Boiling gelatin weakens its setting power, so keep the mixture hot but not boiling at this stage.
