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 Butter
Ingredients
Directions
Prepare the apples
Wash and core the apples.
Cook the apples thoroughly with the cider.
Pass the mixture through a colander to remove solids.
Cook the butter
Place the strained mixture in a pot and add the sugar.
Stir constantly while cooking over medium heat to prevent burning.
After 2-3 hours, check the consistency; if watery, continue cooking until thick.

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
- Pippin apples
- Provide the bulk of the pulp, which breaks down into the thick, spreadable body of the butter.
- Sweet fresh cider
- Supplies liquid that softens the apples so they can be cooked into a smooth purée.
- White sugar
- Adds sweetness and, as the mixture reduces, helps it thicken into a spreadable texture.
The step that matters
Stirring constantly over medium heat. Thick fruit mixtures scorch easily on the bottom of the pot, and burnt sugar gives a bitter taste that spreads through the whole batch. Constant stirring keeps the sugar and pulp moving so they reduce evenly.
