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

What each ingredient does

Grapes
Provide the pulp, skins and natural pectin that give the jam its body and flavor.
Sugar
Sweetens the jam and, as it concentrates, helps it thicken and keep.

The step that matters

Stew until the seeds separate. Stewing softens the pulp so the seeds loosen and can be pressed out. Overcooking can scorch the sugar-rich pulp and dull its fresh grape flavor.

Swap the bitter orange

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

  1. Figfits better
  2. Vanillafits better
  3. Mangofits better
  4. Bitter orangethe original

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