Why it works: Lemon and ginger match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 5,154 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Watermelon Rind Preserves
Ingredients
Directions
Prepare the rinds
Pare off the outside green rind, cut into pieces two inches long, weigh, and throw into cold water.
Skim out and add a heaping teaspoon each of salt and pulverized alum to two gallons of rinds, let stand until salt and alum dissolve.
Fill the kettle with cold water, place on top of stove where it will slowly come to a boil, covering with a large plate so as to keep rinds under.
Boil until they can be easily pierced with a fork.
Make and strain a strong ginger tea, take out rinds, put in tea, and let remain all night.
Make the syrup and cook
Drain, add fresh strained ginger tea, add rind of four lemons cut thin, boil a few moments, skim out and make a syrup of the sugar (one pound to each pound of fruit) and a sufficient quantity of water.
Add the rinds with the four lemons sliced, and a few pieces of white race ginger, and boil gently one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Watermelon rinds
- Provide the bulk of the preserve, becoming tender and translucent as they cook in syrup.
- Sugar
- Sweetens the preserve and, in syrup, helps preserve the rinds and give them their glossy texture.
- Lemons
- Add acidity and a bright citrus aroma that balances the sweetness.
The step that matters
Boiling the rinds until tender. Rinds must be pierced easily with a fork before syrup is added. Undercooked rind stays tough and fibrous, while overcooking makes it fall apart.
Swap the apple
How well each one fits the dish's main ingredients (sugar, lemon, egg, butter, ginger):
- Orangefits better
- Limefits better
- Vanillafits better
- Applethe original
Fit is the average pairing score against sugar, lemon, egg, butter, ginger. Candidates are from the same food group and used in at least 100 recipes.
