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 gel as it cools.
- Strong coffee
- Provides the main coffee flavor and color of the gelatin.
- Sugar
- Adds sweetness and balances the bitterness of the coffee.
The step that matters
Soak the gelatin in cold water. Gelatin must hydrate fully in cold water before hot liquid is added, so it dissolves evenly. Adding it dry or skipping the soak can leave lumps and weak setting.
