Why it works: Lemon and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Preserved Pumpkins
Ingredients
Directions
Prepare the pumpkin
Use equal proportions of sugar and pumpkin, and one gill of lemon juice.
Cut the pumpkin in two, peel and remove the seed, cut into pieces about the size of a fifty‑cent piece.
After weighing, place in a deep vessel in layers, first sprinkling a layer of sugar then a layer of pumpkin, and so on, until finished.
Add the lemon juice and set aside for three days.
Make the syrup and preserve
For every three pounds of sugar, add half a pint of water and boil until tender.
Pour into a pan, setting aside for six days.
Pour off the syrup and boil until thick, skim and add the pumpkin while boiling.
Bottle in the usual manner.
Nutrition, whole recipe (rough)
Counts 2 of 3 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.

Shared aroma: 2-nonenal (fatty, green).
Lemon and sugar barely smell alike, yet cooks put them together in 53,532 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 (in the method)
- Forms the main body of the preserve, softening as it is boiled in syrup.
- Sugar
- Draws out moisture and, once boiled thick, preserves the pumpkin and gives sweetness.
- Lemon juice
- Adds acidity that brightens the flavour and helps the preserve keep.
The step that matters
Boiling the syrup until thick. Sugar must be concentrated enough to preserve the fruit; if the syrup is too thin, the pumpkin can spoil. Skimming removes foam so the syrup stays clear.
