Why it works: Tomato and beans 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 ↓

Ingredients
Directions
Make the broth
In a large pot, combine the beef shank, mutton, cold water, and salt.
Boil until the meat shreds and the liquid reduces to about half.
Remove the large bones from the pot.
Add the vegetables and rice
Add the carrot, onions, and rice (or tomatoes, beans, and celery if using).
Boil for 1 hour.
Strain and chill
Strain thoroughly, pressing out all juices with a potato masher.
Set the strained liquid in a cold place to jelly.
Once cold, remove the fat from the surface.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shank
- Breaks down during boiling to give the broth its body and meaty flavour.
- Mutton
- Adds rich meat flavour and body to the broth as it simmers down.
- Rice
- Thickens the soup slightly as its starch releases during the hour of boiling.
- Onions
- Release sweetness and savoury depth into the broth as they cook.
The step that matters
Boil until the meat shreds and the liquid reduces to about half. Simmering long enough breaks down the connective tissue in the tough cuts, turning them tender and gelatin-rich. Reducing concentrates the flavour, which is needed for the broth to set into a jelly once chilled.
Swap the tomato
