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 ↓
Carrot Soup
Ingredients
Directions
Prepare the soup
Slice the carrots and place them in a saucepan with the onion, celery, and broth.
Add the bones if available and cover the saucepan.
Simmer over moderate heat for 2.5 to 3 hours until the vegetables are soft.
Strain and season
Strain the mixture through a sieve, pressing the vegetables to extract the pulp.
If the soup is too thick, thin it with additional broth or hot water.
Season with salt and pepper, then bring to a boil again.
Serve
Serve with toasted bread cut into dice or fry stale bread slices in a little fat until light brown, then drain and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Main body of the soup, giving sweetness, colour and pulp when pressed through a sieve.
- Onion
- Adds savoury depth and aroma as it softens in the broth.
- Broth
- Forms the liquid base that carries the flavour and cooks the vegetables.
- Celery
- Contributes aromatic, savoury flavour to the broth.
The step that matters
Simmering until the vegetables are soft. Vegetables must be fully softened so they break down easily when pressed through the sieve; undercooked carrots leave a grainy, thick pulp and a weaker flavour.
Swap the onion
How well each one fits the dish's main ingredients (carrot, celery, meat, pepper, bread):
- Capsicumfits better
- Tomatofits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against carrot, celery, meat, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
