Cook the beans

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

What each ingredient does

Kidney beans
Become tender and add body and substance to the finished sauce.
Butter
Carries the browning that gives the sauce its colour and nutty flavour.
Flour
Thickens the liquid into a smooth sauce once stirred into the browned butter.
Soup meat
Flavours the bean cooking water that becomes the base of the sauce.

The step that matters

Browning the butter and flour. Cooking the butter and flour together until deeply brown develops colour and roasted flavour, but it can scorch quickly. Stirring constantly keeps the roux even, and the flour must cook long enough to lose its raw taste before liquid is added.

Swap the kidney beans

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

  1. Almondfits better
  2. Sesamefits better
  3. Beansfits better
  4. Kidney beansthe original

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