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 ↓
Cream of Vegetable Soup
Ingredients
Directions
Prepare the vegetables
Combine carrots, turnips, celery, onion, and potatoes in a pot.
Add boiling water and cook slowly for one hour.
Drain the vegetables, reserving the liquid.
Pass the vegetables through a vegetable press and add to the reserved liquid.
Make the cream base
In a separate pan, melt the butter, then stir in the flour until well blended.
Gradually add the milk, mixing thoroughly.
Combine the milk mixture with the vegetable pulp and liquid.
Heat the soup, boiling for a few minutes to cook the flour, then serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the soup with fat and carries flavour, and forms the base of the roux.
- Flour
- Thickens the milk and butter into a smooth, body-giving base.
- Milk
- Creates the creamy liquid that gives the soup its smooth, rich texture.
- Potatoes
- Break down during cooking to add starch and body to the soup.
- Carrots
- Add sweetness and colour, and thicken the soup as they break down.
- Turnips
- Add earthy flavour and, once pressed, contribute body to the soup.
The step that matters
Cooking the flour after adding the milk. Flour must be boiled for a few minutes to cook out its raw, pasty taste and to reach full thickening. Serving too early leaves the soup tasting floury and thinner than intended.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, celery, potato, butter, flour, milk):
- Leekfits better
- Parsnipfits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against carrot, turnip, celery, potato, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
