Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the liquid into a firm, wobbly jelly as it cools.
- White sugar
- Adds sweetness and helps balance the bitterness of the coffee.
- Coffee
- Provides the flavor and dark color of the jelly.
The step that matters
Stirring until the gelatin and sugar dissolve. Undissolved gelatin granules will not set evenly, leaving grainy or weak spots in the jelly. Stirring fully in warm liquid lets the gelatin hydrate and disperse before cooling.
