Cook
Place the beef in a large pot with 10 gallons of water and boil for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main protein; long simmering breaks down its connective tissue so it becomes tender.
- Potatoes
- Absorb the cooking liquid and thicken the broth as their starch releases during boiling.
- Tomatoes
- Add acidity and body to the broth, balancing the richness of the beef.
The step that matters
Boiling the vegetables until tender. Adding the vegetables too early or cooking them unevenly can leave some pieces hard while others turn mushy. Cut pieces to a similar size and check for tenderness before moving on.
Swap the onion
How well each one fits the dish's main ingredients (beef, potato, carrot, tomato, pepper):
