Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grapes
- Provide the main flavour and the juice that forms the body of the jelly.
- Lemons
- Add acidity that brightens the flavour and balances the sweetness of the syrup.
- Syrup
- Adds sweetness and helps the jelly taste rounded.
- Isinglass
- Acts as a gelling agent so the juice sets firm enough to cut.
The step that matters
Mix in the prepared isinglass. Isinglass is a gelatin-like setting agent, so it needs to be evenly dispersed through the warm juice before setting. Uneven mixing can leave weak or lumpy patches where the jelly fails to firm up.
Swap the grape
How well each one fits the dish's main ingredients (lemon, syrup):
- Orangefits better

Fit is the average pairing score against lemon, syrup. Candidates are from the same food group and used in at least 100 recipes.
