Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Isinglass
- Sets the liquid into a firm jelly as it cools.
- Lump sugar
- Sweetens the juice and helps give the syrup body and a set texture.
- Seville oranges
- Provide tart, aromatic juice and bitter-edged flavor for the jelly.
- Lemons
- Add acidity that brightens the flavor of the citrus juice.
The step that matters
Boiling the syrup until it almost candies. Boiling concentrates the sugar so the syrup is thick enough to flavor and firm the jelly. Overcooking it can make the set too hard and sticky, while underheating leaves the mixture too thin to set properly.
