Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Isinglass
Gelatin that sets the liquid into a firm, sliceable jelly as it cools.
Lump sugar
Adds sweetness and, when boiled, thickens the citrus juice into a syrup.
Seville oranges
Provide bitter, aromatic juice and rind flavor that defines the jelly.
Lemons
Add acidity that brightens the flavor and balances the sweetness.

The step that matters

Add the syrup to the jelly and boil for a moment. Gelatin sets only when the mixture is hot enough to dissolve it fully but not boiled so long that its setting strength weakens. Boiling briefly after combining keeps the jelly liquid enough to strain and pour while still able to set firmly on cooling.

Swap the lemon

How well each one fits the dish's main ingredients (orange, sugar, gelatin):

  1. Vanillafits better
  2. Lemonthe original
  3. Mangofits about as well
  4. Figfits about as well

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