Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
White Vegetable Soup
Ingredients
Directions
Make the soup base
Melt the butter in a pot over medium heat.
Add the carrot, turnip, onion, and celery (or celery seeds) and sauté for 3-4 minutes.
Add the bay leaf, celery seeds, and stock.
Bring to a gentle boil.
Cook for 45 minutes or until the vegetables are tender.
Thicken and finish
Mix the flour with a little milk to form a smooth paste.
Stir in the remaining milk and pour into the soup, stirring until boiling.
Boil for about 6 minutes, stirring continuously.
Season with salt and pepper, remove the bay leaf and celery seeds, and add more stock or milk if too thick.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk and soup into a smooth, creamy body when heated.
- Butter
- Carries the flavor of the vegetables and enriches the soup with fat.
- Milk
- Adds creaminess and a mild sweetness to the white soup.
- Stock
- Provides the liquid base and savory depth for the soup.
- Onion
- Builds aromatic sweetness as it softens in the butter.
The step that matters
Stirring the flour paste into the soup. Flour clumps if added dry or without first being blended smoothly with liquid. Mixing it with a little milk first, then stirring while the soup boils, lets the starch disperse and thicken evenly.

Fit is the average pairing score against carrot, turnip, celery, butter, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
