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 ↓
Brandied Green-gage Plums
Ingredients
Directions
Prepare the plums and leaves
Wash and dry the plums.
Wash and drain the leaves.
In a preserving kettle, place a layer of leaves three deep.
Weigh the plums and add a piece of alum for each pound.
Layer the plums and leaves in the kettle, sprinkling pulverized alum among them.
Cover the last layer of plums with three layers of leaves.
Pour just enough cold water to cover the plums.
Steam the plums
Cover the kettle with a clean towel and a tight lid to keep in steam.
Place the kettle on the back of the stove to heat gradually and steam for two hours.
Do not allow the plums to boil.
Once the plums are quite green, drain and cool them.
Place the plums in wide-mouthed glass jars.
Make the syrup and bottle
For the syrup, combine half a pound of sugar and half a pint of water in a preserving kettle.
Boil and skim the syrup until clear, then cool it.
Add an equal measure of French brandy to the cooled syrup.
Fill the jars with syrup and cork and seal them tightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green-gage plums
- Form the fruit that is candied and preserved in the brandy syrup.
- Alum
- Firms the plum flesh so it holds its shape during steaming and soaking.
- Sugar
- Sweetens the syrup and helps preserve the fruit.
- French brandy
- Adds alcohol and flavour to the syrup, aiding preservation.
The step that matters
Do not allow the plums to boil. Gentle steaming below a boil keeps the fruit intact and firm; boiling would break the skins and soften the flesh.
Swap the plum
How well each one fits the dish's main ingredients (peach, corn, sugar, brandy):
- Vanillafits better
- Apricotfits better
- Figfits about as well
- Plumthe original
Fit is the average pairing score against peach, corn, sugar, brandy. Candidates are from the same food group and used in at least 100 recipes.
