Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Vegetable Soup
Ingredients
Directions
In a pot, combine the stock and boiling water.
Add the chopped onion, carrot, turnip, and cabbage.
Cook the vegetables in the stock until tender. Alternatively, cook the vegetables in boiling salted water first, then add them to the stock.
Stir in the strained tomato, parsley, salt, and pepper.

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.
