Why it works: Gelatin and sugar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,778 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Coffee Jelly
Ingredients
Directions
Make the jelly
Soak the gelatin in cold water for 30 minutes.
Dissolve the soaked gelatin in boiling water and strain through a sieve.
Add sugar and strong coffee to the gelatin mixture. Stir in the vanilla.

Fill the center of the mold with sweetened whipped cream flavored with vanilla.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Granulated gelatin
- Sets the coffee liquid into a firm, wobbly jelly when chilled.
- Strong coffee
- Provides the main coffee flavor and liquid for the jelly.
- Sugar
- Adds sweetness that balances the bitterness of the coffee.
The step that matters
Dissolve the soaked gelatin in boiling water. Gelatin must be fully dissolved before the coffee and sugar are added, or it will not set evenly and may leave grainy specks. Straining removes any undissolved bits.
