Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whisked whites are stirred in and then clarify the jelly as it is strained through the bag.
- Sugar
- Sweetens the jelly and helps give it body and a clear, set texture.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness of the wine and sugar.
- Calf's-foot jelly
- Provides the gelatin that lets the liquid set into a firm jelly once cooled.
- Sweet wine
- Adds flavour and liquid to the jelly base.
- Peaches
- Provide fruit flavour and body within the set jelly.
The step that matters
Clarifying the jelly through the egg whites. Egg whites coagulate when heated and trap cloudy particles as they set, so the jelly runs clear through the bag. Skipping the boil or hanging too early leaves the jelly cloudy.
