Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Isinglass jelly
- Provides the gel structure that lets the jelly set firm.
- Lump sugar
- Sweetens the jelly and, boiled into syrup, adds body to the mixture.
- Lemons
- Add acidity and aroma from both the juice and the grated rind.
- Seville oranges
- Add sharp citrus acidity and fragrant oil from the rind.
The step that matters
Adding the syrup to the isinglass and boiling again. Prolonged boiling can weaken a gelatin-type gel's setting power, so the mixture should be heated only enough to combine evenly and stay hot before pouring.
