Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Stock
Forms the liquid base that carries the flavor of the soup.
Onion
Adds savory sweetness and aroma as it softens in the broth.
Carrot
Adds sweetness and firm texture after simmering until tender.
Cabbage
Adds body and a mild sweetness as it cooks until tender.
Strained tomato
Adds acidity and color, giving the broth a richer flavor.

The step that matters

Cooking the vegetables until tender. Vegetables cooked in the stock need enough time for starches and fibers to soften, so they become tender without turning mushy. Adding the tomato after the vegetables are cooked keeps its bright flavor fresh.
