Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Watermel Pickle
Ingredients
Directions
Prepare the rind
Soak the watermelon rind in a weak brine overnight.
Rinse the rind well.
Drop it into strong boiling alum water (1 tablespoon alum in 2 quarts water). Let it stand for 15 minutes.
Drop it into ice water until cold.
Make the syrup and pickle
Make a syrup by boiling 1 cup sugar in 1 quart water. Drop the melon into the boiling syrup.
Simmer for 6 to 8 hours.
Pour off the syrup.
Place the melon into a new syrup made of 2 cups vinegar and 6 cups sugar. Add the tied spices. Boil thoroughly.
Let the mixture sit overnight in the syrup.
Jar and seal
The next morning, fill jars with the melon. Pour the boiling syrup over it. Seal the jars.

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 translucent as it absorbs the sugar syrup.
- Coarse sea salt
- Draws water out of the rind in the weak brine, firming its texture before further treatment.
- Powdered alum
- Firms the rind's flesh so it stays crisp through long simmering.
- Sugar
- Sweetens the pickle and, at high concentration, preserves the melon in the syrup.
- Vinegar
- Adds acidity that sharpens the flavor and helps preserve the pickle.
The step that matters
Simmering for 6 to 8 hours. Rind must be cooked long enough to turn translucent and absorb syrup, but not so hard it breaks apart. Watch for gentle simmer rather than a rolling boil.
