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 ↓
Good Vegetable Soup
Ingredients
Directions
Prepare the barley

Put the soaked barley into a stew pan with the soup stock and simmer gently for one hour.
Prepare and cook the vegetables

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Softens into chewy grains that thicken the soup and add body.
- Potato
- Its starch softens and helps give the soup a thicker, more substantial body.
- Tomato
- Adds acidity and moisture, brightening the flavor of the broth.
- Carrot
- Adds natural sweetness and color to the soup.
The step that matters
Simmer the barley gently for one hour. Gentle heat lets the barley grains soften evenly and release starch slowly, which thickens the stock. A hard, rolling boil can break the grains apart and make the soup cloudy and mushy.
