Why it works: Apple and cider are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 1,238 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked apples
- Provide the bulk and main fruit flavour, breaking down into the thick spread as they cook.
- Brown sugar
- Adds sweetness and caramel notes, and helps thicken the spread as it reduces.
- Cider vinegar
- Adds acidity that brightens the sweetness and balances the rich, cooked-down flavour.
The step that matters
Boil the mixture until it reduces to about 2 gallons. Water must evaporate slowly for the mixture to thicken into a spreadable butter. Stopping too early leaves it runny, while over-reducing can scorch the sugars on the bottom of the pot, so it needs regular stirring.
