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 ↓
Modern Cookery
Ingredients
Directions
The book says “a very cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Prepare a pan of cold water.
Cook
If using the oven, place the plums in a baking dish and sprinkle the sugar on top without shaking it down.
Bake for 4 to 5 hours.
If using the water method, place the plums with a little hay in a pan of cold water and boil gently for about 3 hours.
Rest and store
Leave the plums in the syrup for a few days to absorb the sugar.
When ready to store, tie a bladder over the necks of jars or bottles and secure with paper or cork.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Plums
- Provide the fruit itself, which softens and holds its shape while cooking slowly in syrup.
- Sugar
- Draws water out of the fruit and forms a syrup that helps preserve it and adds sweetness.
The step that matters
Bake for 4 to 5 hours at a low oven temperature. Slow, gentle heat lets the sugar draw moisture from the plums and thicken the syrup while the fruit stays whole. Higher heat would risk scorching the sugar before the fruit is cooked through.
