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

What each ingredient does

Watermelon rind
Forms the bulk of the pickle and absorbs the syrup as it softens.
White sugar
Adds sweetness and helps preserve the rind in the syrup.
Vinegar
Adds acidity that gives the pickle its tang and helps preserve it.
Cloves
Contributes warm, aromatic spice flavour to the syrup.
Cinnamon
Contributes sweet, warm spice flavour to the syrup.

The step that matters

Pouring the boiling hot syrup over the rind. The syrup must be boiling hot so it penetrates the softened rind and seasons it thoroughly. Repeating the pour over three consecutive days lets the flavour and sweetness soak deeper into the rind.

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.
