Why it works: Syrup and sugar match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Pine-Apple Marmalade
Ingredients
Directions
Prepare the pineapple
Remove the skin from the pineapple and cut the fruit into pieces.
Pound the pieces in a mortar and pass them through a fine sieve.
Weigh the pulp and measure out 1 pint of syrup for every pound of pulp.
Make the marmalade
Boil the syrup until it reaches a rolling boil.
Add the pulp to the boiling syrup and continue to boil until it jellies, similar to apricot marmalade.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pineapple
- Supplies the fruit pulp that forms the body of the marmalade.
- Syrup
- Provides sweetness and moisture, and helps the pulp set as it cooks down.
- Sugar
- Sweetens the marmalade and helps it set into a jelly as it boils.
The step that matters
Boiling the pulp in the syrup until it jellies. The mixture must be boiled long enough for enough water to evaporate and for the pectin and sugar to set. Stopping too early leaves a runny marmalade, while boiling too long can darken and over-thicken it.
Swap the pineapple
How well each one fits the dish's main ingredients (syrup, sugar):
- Vanillafits better
- Raisinfits better
- Pearfits about as well
- Pineapplethe original
Fit is the average pairing score against syrup, sugar. Candidates are from the same food group and used in at least 100 recipes.
