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
Scrape and wash the carrots, then peel off the red outside.
Chop the onion and add it to a gallon stew-pan with the carrots and celery.
Pour in the broth and cover the pan.
Cook and strain
Cook on low heat for 2.5 hours until the carrots are soft.
Optionally, add 1 cup of bread crumbs and boil for 2-3 minutes.
Rub the mixture through a fine sieve with a wooden spoon, adding more broth to achieve a thick consistency.
Serve
Heat the soup in a clean stew-pan, season with salt, and serve with toasted bread on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Form the main body of the soup and give it sweetness and colour.
- Broth
- Provides the liquid that softens the vegetables and carries the flavour of the soup.
- Celery
- Adds savoury aroma and flavour to the base as it cooks.
- Onion
- Adds savoury aroma and depth of flavour as it softens in the pan.
The step that matters
Rubbing the mixture through a fine sieve. The cooked vegetables must be soft enough to pass through the sieve smoothly. Pushing them through gives the soup a smooth, thick texture, and adding broth adjusts the consistency if it is too stiff.
Swap the onion
How well each one fits the dish's main ingredients (carrot, celery, beef, bread):

Fit is the average pairing score against carrot, celery, beef, bread. Candidates are from the same food group and used in at least 100 recipes.
