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

What each ingredient does

Concord grapes
Provide the fruit base, with natural pectin and acid that help the preserve set.
Sugar
Adds sweetness and, as water evaporates, helps the mixture thicken and keep.
Sultana raisins
Add concentrated sweetness and a soft, chewy texture.
Black walnut meats
Add a firm, crunchy texture and a distinct nutty flavor.
Orange conserve
Adds citrus aroma and brightness that balance the sweetness.

The step that matters

Boil slowly for one hour. Long, gentle simmering evaporates water and concentrates the sugar and grape pectin so the mixture thickens. Stopping early leaves it runny, while boiling too hard risks scorching the sugar on the bottom of the pot.

Swap the raisin

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

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

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