Why it works: Clove and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓
Watermelon Rind Pickle
Ingredients
Directions
Prepare the rind

Soak the rind in weak saltwater for 24 hours.
Boil the rind in water until tender, then drain.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Watermelon rind
- Forms the pickle itself, becoming tender and absorbing the syrup's flavour.
- Sugar
- Adds sweetness and helps preserve the rind in the syrup.
- Vinegar
- Adds acidity that gives the pickle its sharp, tangy character.
- Cinnamon
- Contributes warm, aromatic spice flavour to the syrup.
- Cloves
- Contributes strong aromatic spice flavour to the syrup.
The step that matters
Boil the rind until tender, then drain. Rind must be fully softened before syrup is added, because the thick rind resists softening once pickled. Under-boiling leaves it tough, while over-boiling makes it mushy and collapse.
Swap the clove
How well each one fits the dish's main ingredients (sugar, vinegar, cinnamon, ginger, tea):
- Cardamomfits about as well
- Clovethe original
- Allspicefits about as well
- Nutmegfits less well
Fit is the average pairing score against sugar, vinegar, cinnamon, ginger, tea. Candidates are from the same food group and used in at least 100 recipes.
