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
Prepare the kettle
Clean a large brass kettle with vinegar and salt.
Dry the kettle with a fine cloth.
Cook the cider
Fill the kettle with new cider that has not begun to ferment.
As the cider begins to boil, skim it well.
Continue to skim whenever additional cider is added.
Pare, quarter, and core the sweet apples, using 1 bushel for every barrel of cider.
Dip out enough cider to add the apples.
Continue boiling until all cider is added.
Once the apples are in, reduce the heat.
Stir constantly until only about 10 gallons remain.
Use a long stirring board to keep your distance from the heat while stirring to prevent burning.
Jar and seal
While hot, pour the apple butter into stone jars.
Once cooled, cut white paper to fit the jars.
Wet the paper with whiskey.
Place the paper on the butter.

What each ingredient does
- Sweet apples
- Break down into pulp that thickens the butter and gives it its body.
- New cider
- Cooks down into a concentrated, sweet-tart liquid that becomes the butter's flavor and body.
The step that matters
Stir constantly until only about 10 gallons remain. Sugars in the reduced cider and apple pulp scorch easily on the hot metal base, leaving burnt flavor. Constant stirring keeps the mixture moving and spreads heat evenly as it thickens.
