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

What each ingredient does

Mashed berries
Provide the main fruit flavour and colour for the preserve base.
Stoned cherries
Add body and fruit flavour, softening under boiling sugar into the preserve.
Sugar
Adds sweetness and, as it boils down, helps the preserve thicken and keep.
Pure vinegar
Adds acidity that sharpens the flavour and helps preserve the final product.

The step that matters

Boil until thick. Cooking the mixture down concentrates sugar and fruit solids so it sets to the right consistency. Stopping too early leaves it runny and more prone to spoiling, while overcooking makes it stiff and sticky.

Swap the mace

How well each one fits the dish's main ingredients (cinnamon, pepper, mustard, vinegar, sugar, ginger, clove):

  1. Allspicefits better
  2. Cardamomfits better
  3. Nutmegfits better
  4. Macethe original

Fit is the average pairing score against cinnamon, pepper, mustard, vinegar, sugar, ginger, clove. Candidates are from the same food group and used in at least 100 recipes.
