Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef
- Provides the main meaty body and browned savory flavor once seared.
- Red kidney beans
- Add body, texture and starch that thickens the chili as it cooks.
- Tomatoes
- Add acidity and moisture that form the base of the sauce.
- Onions
- Add sweetness and aroma as they soften and brown in the fat.
The step that matters
Searing the ground beef. Stirring until the beef sears browns its surface through the Maillard reaction, building deeper flavor than gray, steamed meat would give. Breaking it up and letting it sit briefly helps it brown rather than release liquid.
Swap the kidney beans
How well each one fits the dish's main ingredients (beef, tomato, onion, pepper):
- Beansfits better
- Black-eyed peafits better
- Chickpeafits better
- Kidney beansthe original
Fit is the average pairing score against beef, tomato, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
