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, sliceable jelly as it cools.
- Sugar
- Sweetens the jelly and balances the sharpness of the lemon juice.
- Lemon juice
- Adds acidity and bright lemon flavor to the jelly.
- Green pepper
- Adds crisp texture and fresh, grassy flavor to the set jelly.
- Stuffed olives
- Add salty, briny bites that contrast with the sweet jelly.
- English walnut meats
- Add crunch and a nutty flavor throughout the jelly.
The step that matters
Strain the mixture and chill until it begins to thicken. Chilling only until it starts to thicken keeps the gelatin from setting before the vegetables and walnuts are folded in. If it is too thick, the pieces will not distribute evenly. If it is still too thin, the pieces will sink and the jelly may not set firmly.
