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
Wash, peel, and quarter the apples, then place them in a pot with water and cook until tender.
Once the apples are cooked, stir in the boiled cider.
Sweeten to taste and continue stirring for about 5 hours until the mixture thickens.

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
- Sweet apples
- Break down into soft pulp that forms the body of the butter.
- Boiled cider
- Adds concentrated apple flavour and sweetness while thickening the mixture as it reduces.
- Sugar
- Adds sweetness and helps the finished butter taste rounded and balanced.
The step that matters
Long, steady stirring until thickened. Apple butter thickens only as water evaporates over a long cook. Stopping early leaves it thin, while stirring too little can let the bottom scorch as sugars concentrate.
