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

What each ingredient does

Grapes
Provide the main fruit body and flavor of the preserve.
Sugar
Sweetens the preserve and helps it thicken and keep as it cooks down.
Seeded raisins
Add concentrated sweetness and chewy body to the preserve.
Lemons
Add acidity that brightens flavor and helps set the preserve.
Walnuts
Add crunch and a toasty, nutty flavor at the end.

The step that matters

Add chopped nuts just before removing from heat. Nuts added too early over long cooking lose their crunch and can taste stale or bitter. Adding them at the end keeps their texture and fresh flavor in the finished preserve.

Swap the raisin

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

  1. Figfits better
  2. Cranberryfits better
  3. Vanillafits better
  4. Raisinthe original

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