Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the coffee liquid into a firm, sliceable jelly.
- Boiling coffee
- Provides the main flavour and liquid base of the jelly.
- Sugar
- Sweetens the coffee jelly and the whipped cream.
- Cream
- Adds richness and a light, airy topping when whipped.
The step that matters
Strain the mixture into a mold and let it set. Gelatine only sets properly when it is fully dissolved and the mixture is cooled but still liquid enough to pour. Straining removes any undissolved gelatine lumps, which would leave a grainy, uneven jelly.
