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 ↓
Mock Turtle Soup
Ingredients
Directions
Make the stock
Gently stew 4 pounds of beef in 1 gallon of water with carrots, onion, celery, herbs, mace, peppercorns, and salt until the meat is in fragments.
Strain the broth and pour it over 3 pounds of veal in a pot; simmer until the meat falls from the bones.
Remove the brains from the calf's head, bone it, and optionally stew the bones with the veal for richer stock.
Strain the soup through a fine sieve into a clean pan and let it cool to remove fat.
Finish and serve
Roll the head with the tongue inside, secure it with twine, and pour the soup over it.
Bring the soup to a gentle boil, skim well, and simmer for 1 to 1¼ hours.
Transfer the head to a deep pan or tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shin or neck
- Breaks down into fragments during stewing, giving the soup its body and rich meaty flavour.
- Veal knuckle or neck
- Adds gelatin-rich bones and meat that thicken the stock and give it a silky mouthfeel.
- Calf's head
- Contributes gelatin and richness, so the soup sets firm and luxurious when chilled.
- Carrots
- Release sweetness and aromatic depth into the broth during the long stew.
- Onion
- Adds savoury sweetness and aroma to the stock as it simmers.
The step that matters
Cooling and skimming the soup. Fat rises and sets on the surface as the soup cools, and it is easier to remove cleanly when cold. Skimming while it simmers keeps the broth clear and prevents greasy, cloudy soup.
Swap the mace
How well each one fits the dish's main ingredients (beef, carrot, onion, celery, veal):
- Parsleyfits better
- Thymefits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against beef, carrot, onion, celery, veal. Candidates are from the same food group and used in at least 100 recipes.
