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 enough water and bring to a boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Releases gelatin and flavor into the broth as it simmers, so the cooled broth sets into a jelly.
- Split peas
- Break down while cooking to thicken the soup and add body.
- Beans
- Add substance and soft, starchy texture to the finished soup.
- Rice
- Absorbs liquid and adds starchy body to the soup.
The step that matters
Reducing the beef broth to 1 gallon. Simmering long enough concentrates the flavor and extracts gelatin from the shin, which is what lets the cooled broth set into a jelly. Too little reduction gives a weak broth that will not gel.
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.
