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 ↓

What each ingredient does
- Plums
- Supply the fruit, which softens and concentrates in flavor during long, gentle heating.
- Sugar
- Draws water out of the fruit and helps preserve it against spoilage.
The step that matters
Keeping the kettle topped up. The boil must stay steady for the whole day. If the outer water runs low, the jar stops being heated evenly and the process is interrupted, so the water should be replenished as it evaporates.
