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 ↓
Apple, Peach and Other Fruit Butters— How to Make
Ingredients
Directions
Prepare
Pare and core the apples.
Boil down the cider to 1½ barrels.
Cook the butter
Place the apples in a copper kettle.
Pour enough boiled cider over the apples to nearly cover them.
Heat the kettle and as the cider boils away, add more until all is used and the mixture reaches a proper consistency.

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.

Shared aroma: ethanol (alcoholic, ethereal).
Apple and sugar barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the bulk of the butter, breaking down into a soft, spreadable pulp as they cook.
- Cider
- Supplies liquid and sugars that concentrate as it boils, sweetening and thickening the butter.
The step that matters
Adding the boiled cider gradually as it boils away. Cider reduces as it cooks, so the mixture can scorch on the bottom of the kettle if it runs dry. Adding more keeps enough liquid present while the apples soften and the sugars concentrate into a thick, even butter.
