Why it works: Cider and apple 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 Butter
Ingredients
Directions
Reduce the cider
Boil the cider until reduced to half its original quantity.
Cook the apples
Pare, core, and slice enough apples to measure 2.5 bushels.
Add the apples to the cider and let them boil, stirring constantly.
Cook until the mixture is a smooth, thick pulp, which will take 9 to 12 hours.
Be careful not to let it scorch.

What each ingredient does
- Cider
- Provides the liquid base and its sweet, tart flavor, which concentrates as it reduces.
- Apples
- Break down into pulp that gives the butter its body, sweetness, and fruit flavor.
The step that matters
Stir constantly and avoid scorching. Apple sugars and pulp settle on the bottom of a wide pot during long cooking and burn easily. Constant stirring spreads the heat and keeps the mixture from sticking, which would otherwise add a burnt taste to the whole batch.
