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 ↓
Brown Soup
Ingredients
Directions
Make the stock
Cook veal knuckles or shanks in 3 quarts of water for 1 hour, skimming off any scum.
Cook carrots, celery, and onion in 1 quart of water for 30 minutes.
Brown and simmer
Brown the meat in a very hot frying pan.
Gradually add some of the soup to the browned meat.
Once dark brown, add the meat mixture to the remaining soup and boil slowly for 1 hour.
Finish and serve
Strain the soup and add the vegetable soup.
Season with salt and pepper.
Serve with carrots cut into small pieces.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckles or shanks
- Release gelatin and meaty flavor into the water, giving the soup body over a long simmer.
- Round steak
- Browns to build deep, savory flavor that colors and enriches the broth.
- Carrots
- Add natural sweetness and aroma to the soup, and are served as pieces in the bowl.
- Onion
- Adds savory aroma and sweetness as it softens in the simmering liquid.
The step that matters
Browning the meat. Meat must be seared in a very hot pan until dark brown, because the Maillard reaction creates the roasted flavors and color that a plain boiled soup lacks. Pale meat gives a flat, grey-tasting broth.
Swap the onion
How well each one fits the dish's main ingredients (veal, carrot, celery, pepper):
- Parsnipfits better
- Capsicumfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against veal, carrot, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
