Why it works: Plum and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 2,313 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Plums, Candied
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare and dry
Cut the plums in half and lay them on a large shallow dish.
Strew powdered sugar over the plums.
Place the plums in a 350°F (175°C) oven, tightly closed.
After 30 minutes, remove the plums.
Place the plums on glass plates to dry.
Prick the skins with a large needle or blanch them in boiling water if removing the skins.
Make the syrup
Prepare a thick syrup with 1½ pounds of sugar for every pound of fruit.
Simmer the plums in the syrup for at least 2 hours without boiling.
Skim out the plums from the syrup.
Boil the syrup down for about 1 hour until thick.
Boil the syrup with ½ pint of cracked kernels for added flavor.
Strain the kernels out of the syrup.
Finish
Scald the plums in alum water.
Pour hot syrup over the plums daily for a week.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Plums
- The main fruit, whose skins and flesh hold their shape and absorb the syrup as it cooks.
- Powdered sugar
- Draws moisture out of the cut fruit and begins sweetening it before the syrup stage.
- Sugar
- Forms a thick syrup that sweetens the fruit and, over time, replaces its water to preserve it.
- Cracked kernels
- Flavors the syrup, adding aroma.
The step that matters
Simmer the plums in the syrup for at least 2 hours without boiling. Gentle heat lets sugar slowly penetrate the fruit and replace its water while keeping the skins intact. Boiling would toughen the skins and break the plums apart.
