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 ↓
Best Sweet Pickle Ever Made
Ingredients
Directions
Prepare the rind
Layer grape leaves and watermelon rinds in a kettle, sprinkling a little alum between layers.
Cover with water and simmer on the back of the stove until clear, then cool on a dish.
Make the syrup and pickle
For every pound of rind, combine 1 pound of sugar, ½ pint of vinegar, cloves, and cinnamon in a pot.
Boil the mixture and pour it over the cooled rind in a jar.
Repeat boiling the vinegar mixture for six mornings.

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 rind
- Forms the bulk of the pickle and becomes tender and translucent when simmered.
- Sugar
- Adds sweetness and helps preserve the rind in the syrup.
- Vinegar
- Adds acidity that sharpens the flavour and helps preserve the pickle.
- Alum
- Firms the rind so it stays crisp through cooking.
The step that matters
Repeated boiling over six mornings. Reboiling the syrup over several days slowly draws sugar and vinegar into the rind, so the pickle cures evenly. Skipping or rushing the repeats leaves the rind less preserved and less flavoured throughout.
Swap the grape
How well each one fits the dish's main ingredients (sugar, vinegar, clove, cinnamon):
- Vanillafits better
- Quincefits better
- Figfits better
- Grapethe original
Fit is the average pairing score against sugar, vinegar, clove, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
