Why it works: Beans and potato match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 655 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White beans
Starchy body that softens during long simmering and, once pressed, gives the soup its texture.
Potatoes
Starch that breaks down during long boiling, adding body to the soup.
Meat stock
Liquid base that carries the savoury flavour of the soup.
Flour or corn flour
Starch that swells in hot liquid to thicken the soup further.

The step that matters

Thicken with flour, then boil for five minutes. Starch must be fully heated to swell and thicken the liquid, and boiling it briefly cooks out the raw floury taste. Stirring in the flour before boiling helps prevent lumps.

Swap the potato

How well each one fits the dish's main ingredients (meat, beans, pepper, flour):

  1. Okrafits better
  2. Spinachfits better
  3. Shallotfits better
  4. Potatothe original

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