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 ↓
To Preserve Peaches Whole
Ingredients
Directions
Prepare the peaches
Pare the peaches or pierce the skin in several places with a coarse needle.
Weigh the peaches and use an equal quantity of sugar.
Make the syrup and cook
Dissolve the sugar in a little water, then boil and skim it well.
Add the peaches to the syrup and simmer until they look clear and the syrup thickens.
Jar and seal
Transfer the peaches to small jars, cover with brandy paper, and seal tightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peaches
- Provide the fruit that is cooked whole and becomes tender and clear in the syrup.
- Sugar
- Sweetens the fruit and, at equal weight to the peaches, draws out moisture and preserves them.
- Brandy paper
- Covers the jar to help seal it and add a light boozy aroma.
The step that matters
Simmering the peaches in the syrup. Simmer gently so the fruit cooks through and turns clear without breaking apart. Boiling hard can split the skins and crack the flesh, while too short a simmer leaves the syrup thin and the fruit unpreserved.
Swap the plum
How well each one fits the dish's main ingredients (peach, sugar, brandy):
- Vanillafits better
- Apricotfits better
- Plumthe original
- Pearfits about as well
Fit is the average pairing score against peach, sugar, brandy. Candidates are from the same food group and used in at least 100 recipes.
