Why it works: Pineapple and apple match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 530 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Pine Apple Jam
Ingredients
Directions
Prepare the fruit
Peel and slice the pineapples thinly to retain juice.
Place the pineapples in a preserving pan with 2 quarts of water and boil sharply for 15 minutes.
Rub the pulp through a fine sieve into a large pan.
Cook the jam
Boil the sugar to the pearl stage, then add the pulp.
Stir while boiling for 15 minutes until it reaches the desired consistency.
Pour the jam into pots.

Apple and sugar barely smell alike, yet cooks put them together in 16,478 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
- Pineapples
- Provide the fruit pulp and natural juice that form the body and flavour of the jam.
- Sugar
- Sweetens the jam and, as it cooks down, helps it thicken and set.
The step that matters
Boiling the sugar to the pearl stage before adding the pulp. Sugar must reach the pearl stage, a specific concentration, so the jam sets properly. Adding pulp too early or under-boiling the sugar can leave the jam runny.
Swap the pineapple
How well each one fits the dish's main ingredients (apple, sugar):
- Pearfits better
- Vanillafits better
- Apricotfits better
- Pineapplethe original
Fit is the average pairing score against apple, sugar. Candidates are from the same food group and used in at least 100 recipes.
