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
Prepare all the vegetables by peeling and cutting them into small thick pieces.
In a saucepan, melt the butter.
Add the sugar, salt, pepper, parsley, and vegetables.
Cook over medium heat for 10 minutes, shaking the pan occasionally.
Make the soup
Add the water and let the soup simmer for 1 hour or until the vegetables are tender, stirring often to prevent burning.
Strain the soup through a wire sieve or colander into a basin.
Rub the vegetables through with a wooden spoon.
Pour the soup back into the saucepan.
Add the milk.
Sprinkle in the sago.
Gently boil the soup for 30 minutes.
Serve
Serve hot with toasted bread or squares of bread fried in dripping.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down when rubbed through, thickening the soup and giving it body.
- Sago
- Swells during boiling, further thickening the soup.
- Butter
- Adds richness and carries flavor as the vegetables cook.
- Milk
- Adds creaminess and softens the flavor of the soup.
- Carrots
- Add sweetness and body as they soften and are puréed.
The step that matters
Rubbing the vegetables through the sieve. Pressing cooked vegetables through a sieve breaks their cell walls into a smooth purée, which thickens the soup. Skipping or rushing this leaves the soup lumpy and thin.
Swap the onion
How well each one fits the dish's main ingredients (turnip, carrot, potato, butter, parsley, milk, sugar):
- Parsnipfits better
- Leekfits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against turnip, carrot, potato, butter, parsley, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
