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 and drop it into strong boiling alum water (1 tablespoon alum to 2 quarts water) for 15 minutes.
Transfer the rind to ice water and let it cool.
Make the syrup and cook
Make a syrup by boiling ½ cup sugar in 1 quart of water.
Drop the rind into the boiling syrup and simmer for 6 to 8 hours.
Pour off the syrup and place the rind into a new syrup made of 2 cups vinegar and 6 cups sugar.
Add spices tied in cheesecloth and boil thoroughly.
Let the mixture sit overnight in the syrup.
Jar and seal
Fill jars with the melon.
Pour the boiling syrup over it and 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 firm, crisp pickled pieces that absorb the syrup.
- Powdered alum
- Helps the rind stay firm and crisp during cooking.
- Sugar
- Sweetens the pickle and draws moisture out of the rind as it cooks.
- Vinegar
- Adds acidity that gives the pickle its sharp, tangy flavor.
The step that matters
Simmering the rind in syrup. Simmering for 6 to 8 hours lets sugar slowly replace the water in the rind, so it turns translucent and holds its shape. Too brief a simmer leaves the rind tough and under-sweetened.
