Why it works: Beans and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,733 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White beans
- Form the body of the dish and turn tender as they cook in the stock.
- Good stock
- Supplies the savoury cooking liquid that the beans absorb and reduce into a glaze.
- Brown sauce
- Adds colour and savoury depth to the beans as they are shaken through it.
The step that matters
Boiling until nearly glazed. As the stock reduces, its sugars and proteins concentrate and can scorch on the pan, so the beans must be watched and stopped when the liquid turns syrupy and coats them.
Swap the beans
How well each one fits the dish's main ingredients (sauce, sugar, pepper):
- Chestnutfits about as well
- Black-eyed peafits about as well
- Beansthe original
- Sesamefits about as well
Fit is the average pairing score against sauce, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
