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

What each ingredient does

Isinglass
Gelatin-like protein that sets the liquid into a firm jelly as it cools.
Gum arabic
Stabilizes the jelly and helps keep it smooth and evenly textured.
Sugar
Adds sweetness and balances the tartness of the lemon juice and port.
Port wine
Main liquid that gives the jelly its flavor and color.

The step that matters

Melting the isinglass gently in the hot water bath. Isinglass must fully dissolve before cooling, or it will not set evenly. Stirring in the hot water bath gives gentle, even heat, which avoids clumps and scorching.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, port wine, clove):

  1. Figfits better
  2. Vanillafits better
  3. Applefits better
  4. Lemonthe original

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