Why it works: Beans and tomato match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,713 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Mexican Chili Con Carne
Ingredients
Directions
Prepare the beans
Soak the beans in cold water for several hours, then boil until tender, draining off the liquid.
Make the chili
Combine the pork, beef, green pepper, butter or drippings, and onion in a skillet; simmer until tender, then brown.
Add the strained tomatoes and stir well.
Mix the chili powder, salt, white pepper, and mustard together, then add to the skillet.
Cook for 5 minutes after combining all ingredients, then serve hot; add more water if the mixture is too thick.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef and pork
- Provide the main meat texture and savory browned flavor once cooked.
- Kidney or chili beans
- Add body, starchy texture and bulk that makes the dish hearty.
- Strained tomatoes
- Supply acidity and liquid that form the sauce base.
- Butter or drippings
- Carries fat for browning the meat and onion and adds richness.
- Onion
- Adds sweetness and aroma as it softens and browns in the fat.
The step that matters
Simmer and brown the meat before adding tomatoes. Browning the meat and onion in fat builds deep savory flavor through the Maillard reaction. Adding tomatoes too early steams the meat instead of browning it, leaving a flatter taste.
Swap the white pepper
How well each one fits the dish's main ingredients (beans, beef, pork, pepper, butter, onion, tomato):
- Garlicfits better
- Thymefits better
- Cuminfits better
- White pepperthe original
Fit is the average pairing score against beans, beef, pork, pepper, butter, onion, tomato. Candidates are from the same food group and used in at least 100 recipes.
