Why it works: Kidney beans and vinegar work together. They rank in the top 16% of all ingredient pairs, and cooks put them together in 180 recipes. Both carry isoamyl acetate, which smells banana, pear. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidney beans
- Provide the main body and starchy, hearty texture of the dish.
- Melted butter
- Adds richness and fat that coats the beans and carries flavor.
- Vinegar
- Adds a bright acidity that balances the richness of the butter.
The step that matters
Cook until tender. Raw kidney beans contain a toxin that is destroyed only by thorough boiling, so the beans must be cooked fully before they are eaten.
Swap the kidney beans

Fit is the average pairing score against butter, vinegar. Candidates are from the same food group and used in at least 100 recipes.
