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 ↓
Pumpkin Preserved in Pieces
Ingredients
Directions
Prepare the pumpkin
Pare the pumpkin, cut it in half, remove the seeds, and divide each half into 2-inch square pieces.
Place the pieces in a stone jar, add ½ cup of salt, and cover with cold water.
Let it stand for 5 hours.
Drain the pumpkin and cover with fresh cold water.
Soak for 2 hours, changing the water 3 or 4 times.
If desired, dissolve 1 teaspoon of powdered alum in 2 quarts of boiling water. Add the alum solution to the pumpkin and bring to a boil.
If omitting alum, bring the pumpkin to a boil in the water and then drain.
Make the syrup and cook
In a preserving kettle, combine 2½ pounds of sugar and 1½ quarts of boiling water.
Boil and skim until clear.
Add the pumpkin to the syrup and cook gently until tender enough to pierce with a skewer.
Carefully lift each piece with a skimmer and place on a large plate.
Let them stand in the sun for 2 hours to harden.
Chip the yellow rind from the lemon and add it to the syrup along with the lemon juice and sliced ginger.
Boil for 10 minutes and let cool.
Jar and seal
Once the pumpkin is hardened and cold, place it in glass jars.
Bring the syrup to a boil again.
Strain the syrup over the pumpkin.
Seal the jars when cool.

Sugar and ginger 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
- Pumpkin
- Forms the firm, tender pieces that make up the preserve.
- Granulated sugar
- Makes the syrup that preserves the pumpkin and gives it sweetness.
- Coarse sea salt
- Draws water out of the pumpkin during the initial soak, firming its texture.
- Lemon
- Adds acidity and aroma from the zest and juice to the syrup.
- Powdered alum
- Helps the pumpkin pieces keep their firmness during cooking.
The step that matters
Cooking the pumpkin in the syrup gently. Boiling hard can break the pieces apart and make them mushy. Gentle cooking lets the sugar slowly penetrate and firm the flesh while keeping its shape.
Swap the pumpkin
How well each one fits the dish's main ingredients (sugar, lemon, ginger):
- Orangefits better
- Limefits better
- Mangofits better
- Pumpkinthe original
Fit is the average pairing score against sugar, lemon, ginger. Candidates are from the same food group and used in at least 100 recipes.
