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

What each ingredient does

Steak
Provides the main protein and meaty body of the chili.
Kidney beans
Add starch and texture that give the chili body and substance.
Canned tomatoes
Add moisture and acidity that help form the chili's sauce.
Horseradish
Adds a sharp, pungent heat that carries through the simmered dish.

The step that matters

Skimming the foam after the boil. Foam rising from the steak contains proteins and impurities. Skimming it early keeps the broth clear and prevents a scummy, bitter flavour in the finished chili.

Swap the kidney beans

How well each one fits the dish's main ingredients (onion, tomato, horseradish, pepper):

  1. Beansfits better
  2. Black-eyed peafits better
  3. Chickpeafits better
  4. Kidney beansthe original

Fit is the average pairing score against onion, tomato, horseradish, pepper. Candidates are from the same food group and used in at least 100 recipes.
