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 ↓

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 the jars
Combine plums and sugar in a jar, ensuring sugar is added after the fruit without shaking it down.
Seal the jars with a bladder and secure with paper or cork.
Cook and rest
Place jars in a pan of cold water with hay between them, and boil gently for about 3 hours.
Alternatively, bake in a cool oven at 300°F (150°C) for 4 to 5 hours.
Leave the plums in the syrup for a few days before serving.

What each ingredient does
- Plums
- Provide the fruit that is cooked and preserved in its own syrup.
- Sugar
- Sweetens the fruit and draws water out to form a syrup that helps preserve it.
The step that matters
Heat gently. Gentle heat cooks the plums through without breaking them apart or forcing the sealed jars to boil hard and loosen. Slow cooking also lets the sugar syrup penetrate the fruit evenly.
