Why it works: Ginger and mace are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,152 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓

Ingredients
Directions
Prepare the rind
Cut the watermelon rind into desired shapes.
Soak the rind in a strong brine until it floats an egg.
Cover with grape leaves and set aside.
Soak the rind in fresh water, changing it until the salt taste is gone.
Dissolve the alum in 1 gallon of water.
Lay the rind in it, covered with grape or cabbage leaves.
Simmer until it turns a pretty green.
Soak the rind in soft water to remove the alum.
Make the ginger and syrup
Pour boiling water over the ginger and let it soften.
Slice the ginger into thin pieces.
Boil the ginger in ½ gallon of water for 1 hour.
Add the mace and sugar to create a thin syrup.
Cook and repeat
Gently boil the rind in the syrup for 30 minutes. Add water to keep it covered.
Set the kettle aside for 4 days.
Boil again, adding more sugar and water as needed.
Repeat this process 6 or 7 times until the syrup is thick and rich.

Ginger and sugar barely smell alike, yet cooks put them together in 14,054 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 main body of the preserve, absorbing syrup to become tender and translucent.
- Pulverized alum
- Firms the rind's texture and helps it stay crisp during long cooking.
- Best sugar
- Preserves the rind and builds the thick, rich syrup as it concentrates over repeated boiling.
- White ginger
- Adds a warm, pungent aroma and spice flavor to the syrup.
- Mace
- Contributes a warm, aromatic spice flavor to the syrup.
The step that matters
Soaking the rind to remove the alum. Alum firms the rind but leaves a harsh, astringent taste if not fully rinsed out. Soaking in fresh soft water long enough removes the residue before the rind is cooked in sugar syrup.
Swap the mace
How well each one fits the dish's main ingredients (grape, ginger, sugar):
- Cinnamonfits better
- Cardamomfits better
- Clovefits better
- Macethe original
Fit is the average pairing score against grape, ginger, sugar. Candidates are from the same food group and used in at least 100 recipes.
