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 and meaty flavour that the broth carries.
Rice
Thickens the soup slightly as its starch releases during boiling and adds body.
Potatoes
Soften during long boiling and add starch, making the soup heartier.
Onion
Adds aromatic sweetness and depth as it cooks into the broth.
Tomato
Adds acidity and savoury flavour that brightens the broth.

The step that matters

Adding the vegetables and rice at the halfway point. Beef needs a long simmer to become tender, while rice and potatoes break down quickly. Adding them only once the beef is half cooked lets everything finish together without turning mushy or leaving the meat tough.
