Why it works: Pineapple and lemon are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 1,964 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Pine Apple Marmalade
Ingredients
Directions
Prepare
Cut, pare, and weigh the pineapple.
Grate the pineapple and press it through a colander, saving all the juice.
Cook the marmalade
Add 1 pint of water for every 3 pounds of fruit and boil until tender.
Add 2¼ cups of sugar and the juice of 1 lemon to the mixture.
Add the saved pineapple juice and boil for about 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pineapple
- Provides the bulk of the fruit, flavour and body of the marmalade.
- Sugar
- Adds sweetness and helps preserve the marmalade while it thickens.
- Lemon juice
- Adds acidity that brightens the flavour and supports thickening.
The step that matters
Boiling after the sugar and lemon juice go in. Sugar and acid must be boiled together with the fruit long enough to thicken the mixture. Stopping too early leaves a loose, runny marmalade, while boiling too long can darken and over-concentrate the flavour.
Swap the pineapple
How well each one fits the dish's main ingredients (sugar, lemon):
- Orangefits better
- Limefits better
- Vanillafits better
- Pineapplethe original
Fit is the average pairing score against sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
