Why it works: Rice and beans match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,017 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Winter Soup
Ingredients
Directions
Make the broth
Boil the shin of beef in 2 gallons of water until reduced to 1 gallon.
Remove the bones and let the broth cool until it forms a jelly.
Take the desired amount of jelly for soup.
Assemble the soup
Stew the vegetables or cook the rice, split peas, and beans.
Combine everything in a pot with additional water as needed and boil well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Simmered long to release gelatin, which sets the broth into a jelly when cooled.
- Split peas
- Break down during boiling, thickening the soup and adding body.
- Rice
- Absorbs liquid and softens, adding bulk and texture to the soup.
- Beans
- Hold their shape while cooking and add substance and texture to the soup.
The step that matters
Reducing the beef broth. Boiling the shin down to 1 gallon concentrates the broth and its gelatin. Too little reduction leaves a thin broth that will not set into a jelly when cooled.
Swap the peas
How well each one fits the dish's main ingredients (beef, rice, beans):
- Sesamefits better
- Lima beansfits better
- Peanutfits better
- Peasthe original
Fit is the average pairing score against beef, rice, beans. Candidates are from the same food group and used in at least 100 recipes.
