Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Provides the setting structure that turns the liquid coffee into a wobbly jelly.
- Strong coffee
- Supplies most of the flavor and dark color of the jelly.
- Sugar
- Adds sweetness to balance the bitterness of the coffee.
The step that matters
Dissolve the gelatin fully before adding it to the coffee. Gelatin only sets evenly when it is completely dissolved and mixed through the liquid. Undissolved granules or unstirred pockets can leave lumps or soft spots in the set jelly.
