Why it works: Beans and onion match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 5,242 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stewed Beans
Ingredients
Directions
Prepare the beans
Soak the red beans in cold water.
Boil quickly until soft, adding boiling water if necessary.
Fry and stew
In a frying pan, heat the lard.
Add the chopped onion and fry until well cooked.
Add the beans and salt to taste.
Stir in the green pepper or chili pepper.
Continue frying while stirring to prevent burning.
Cover the pan with the bean cooking liquid.
If there's not enough liquid, add boiling water.
Cover and cook slowly until the sauce is reduced to your desired dryness.
Remove the onion before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red beans
- Form the main body of the dish and, once softened, thicken the stew.
- Lard
- Fat for frying that carries flavor and gives the onion a rich base.
- Onion
- Builds savory sweetness as it fries, flavoring the sauce before it is removed.
- Green pepper or chili pepper
- Adds aroma and a fresh, mildly sharp note to the stewed beans.
The step that matters
Continue frying while stirring to prevent burning. The beans and sauce contain sugars and starches that scorch on hot pan bottoms. Constant stirring spreads heat evenly and keeps the sauce from sticking and turning bitter.
Swap the onion
How well each one fits the dish's main ingredients (beans, pepper):

- Onionthe original
Fit is the average pairing score against beans, pepper. Candidates are from the same food group and used in at least 100 recipes.
