Why it works: Onion and beans 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 ↓
Soue Pickled Beans As a Vegetable
Ingredients
Directions
Make the base
Heat the lard in a large pan until very hot.
Add the chopped onion and flour; stir and let brown.
Pour in enough water to create a thick gravy.
Finish the soup
Remove the pickled beans from their juice, cut them, and add to the gravy.
Season with salt and pepper to taste.
If needed, add a little pickle vinegar for extra sourness.
Boil for fifteen minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lard
- Fat that carries heat for browning the onion and flour.
- Flour
- Thickens the liquid into a gravy as it cooks with the water.
- Pickled beans
- Provide the main sour flavour and the body of the soup.
- Onion
- Adds savoury sweetness and aroma as it browns in the fat.
The step that matters
Let the onion and flour brown. Browning the flour in hot fat develops nutty, toasted flavour and colour before liquid is added. If the mixture is not hot enough or is stirred too little, the flour can scorch or stay pale and taste raw.
Swap the onion
How well each one fits the dish's main ingredients (flour, beans, pepper, vinegar):
- Capsicumfits better
- Okrafits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against flour, beans, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
