Why it works: Plum and peach match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 163 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Garfield Butter
Ingredients
Directions
Prepare the fruit
Pare, pit, and slice the peaches.
Remove pits from freestone plums.
Make the butter
Cook the peaches and plums together slowly until soft.
Rub the mixture through a colander or coarse sieve.
Add ¾ cup of sugar for each cup of pulp and cook slowly, stirring often until thick.
Pack the hot butter into sterilized jars and cover with hot paraffin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Plums
- Provide most of the pulp and tart flavour that give the butter its body.
- Peaches
- Add sweet, mellow fruit flavour and extra pulp to the butter.
- Sugar
- Sweetens the fruit and, with long cooking, thickens the pulp into a spreadable butter.
The step that matters
Cooking the pulp with sugar until thick. Sugar must be added to the pulp and cooked slowly, stirring often, so the mixture thickens without scorching on the bottom of the pan. Too little cooking leaves it runny, and too much or too fast heat can burn the sugar.
Swap the plum
How well each one fits the dish's main ingredients (peach, sugar):
- Vanillafits better
- Apricotfits better
- Pearfits about as well
- Plumthe original
Fit is the average pairing score against peach, sugar. Candidates are from the same food group and used in at least 100 recipes.
