Why it works: Pear and plum match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 245 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Mixed Marmalade
Ingredients
Directions
Prepare the fruit
Pare and cut the apples, pears, and plums into small bits.
Stew the fruit in a little water until tender.
Strain the stewed fruit through a fine sieve.
Make the marmalade
Weigh the pulp and add an equal weight of sugar.
Cook the mixture in a thick-lined granite kettle on the stove for three hours.
Stir often for the first two hours and continuously for the last hour to prevent burning.
When the mixture is thick, pour it into shallow pans.
Cover the pans.
Serve
Slice the marmalade.
Place the slices on a plate like cheese.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White apples
- Their pectin and body help the marmalade set and turn thick.
- Yellow pears
- Their soft pulp adds bulk and mild sweetness to the fruit base.
- White plums
- Their fruit and natural acidity add flavour and help the mixture set.
- Sugar
- Sugar thickens the pulp as it cooks down and preserves the marmalade.
The step that matters
Stirring during the long cook. The mixture is thick and sugary, so it scorches easily on the base of the kettle. Frequent stirring, especially in the final hour as it thickens, keeps sugars from burning and helps the marmalade cook evenly.
