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

What each ingredient does

Watermelon rind
Forms the main body of the pickle, becoming tender and translucent as it cooks.
Alum
Firms the rind so it keeps its shape and crispness during long cooking.
Vinegar
Adds acidity that sharpens the flavor and helps preserve the pickle.
Sugar
Sweetens the pickle and, as a thick syrup, helps preserve it and clarify the rind.
Cinnamon bark
Contributes warm, sweet spice aroma that infuses into the syrup and rind.

The step that matters

Boiling the rind in the syrup until clear and tender. Simmering gently lets the syrup slowly penetrate the rind; boiling too hard can break the pieces apart or make the syrup too thick before the rind is fully infused.

Swap the mace

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

  1. Clovefits better
  2. Nutmegfits better
  3. Gingerfits better
  4. Macethe original

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