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

What each ingredient does

Watermelon rind
Forms the firm, tender body of the pickle and absorbs the flavoured syrup.
Sugar
Sweetens the pickle and, in the syrup, draws moisture out to help preserve the rind.
White vinegar
Adds acidity that sharpens the flavour and helps preserve the pickle.
Oil of cloves
Adds a warm, aromatic clove flavour to the syrup.
Oil of cinnamon
Adds a sweet, aromatic cinnamon flavour to the syrup.

The step that matters

Repeating the syrup boil over several days. Reboiling and pouring the syrup back over the rind on each repeat gradually concentrates the sugar and flavour and draws moisture out. Skipping or rushing these repeats can leave the rind under-flavoured and less well preserved.

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.
