Ingredients
Directions
Make the jelly

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the coffee liquid into a firm, sliceable jelly as it cools.
- Strong coffee
- Provides the main flavor and liquid base of the jelly.
- Sugar
- Sweetens the coffee to balance its bitterness.
The step that matters
Strain the mixture through a flannel cloth or jelly bag. Straining removes undissolved gelatin and coffee grounds, so the jelly sets clear and smooth rather than cloudy or gritty.
