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

What each ingredient does

Blackberries
Provide the main fruit body and flavor, softening during cooking to become the pickled fruit.
Sugar
Adds sweetness and, as it dissolves and boils down, thickens the syrup that coats the fruit.
Vinegar
Adds acidity that gives the pickle its sharp tang and helps preserve it.
Ground cinnamon
Adds warm, sweet aroma to the syrup.
Ground cloves
Adds warm, pungent aroma to the syrup.

The step that matters

Boil the syrup until it thickens. Sugar concentrates as water evaporates, so the syrup must reduce enough to thicken and coat the fruit. Under-boiling leaves a thin syrup that spoils sooner, while over-boiling can make it too stiff or sticky.

Swap the clove

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

  1. Allspicefits about as well
  2. Nutmegfits about as well
  3. Clovethe original
  4. Cardamomfits about as well

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