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 Sweet Pickles
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Cut the watermelon into small cubes, removing the rind.
In a pot, combine sugar, vinegar, cloves, cinnamon, allspice, and salt.
Bring the mixture to a boil, stirring until the sugar dissolves.
Cook and jar
Add the watermelon cubes and simmer for 30 minutes.
Pour the pickles into sterilized jars and seal while hot.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Watermelon
- Forms the pickled body of the dish, becoming tender as it simmers in the syrup.
- Sugar
- Provides sweetness and, dissolved into the liquid, helps preserve the pickles.
- Vinegar
- Adds acidity that gives the pickle its sharp tang and helps preserve it.
The step that matters
Dissolving the sugar before adding the fruit. Stirring until the sugar fully dissolves in the boiling vinegar creates an even syrup. Undissolved sugar can crystallize or leave the brine uneven, so the watermelon cooks in a consistent, well-balanced liquid.
Swap the clove
How well each one fits the dish's main ingredients (sugar, vinegar, cinnamon, allspice):
- Clovethe original
- Nutmegfits about as well
- Gingerfits less well
- Cardamomfits less well
Fit is the average pairing score against sugar, vinegar, cinnamon, allspice. Candidates are from the same food group and used in at least 100 recipes.
