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
Prepare the calf's head
Wash the calf's head and boil it for an hour in 6 quarts of water.
Cut the meat into squares while still warm.
Make the broth
In a stewpan, combine the knuckle of veal and 6 lb of beef with 2 carrots, 2 turnips, 2 onions, and 2 heads of celery.
Stew gently for 4 hours in 3 quarts of the broth from the calf's head.
Season and finish
Strain the broth into a large jar and add the squares of calf's head, white pepper, mace, salt, and anchovies.
Stew in the oven for 2 hours, then transfer to a stewpan with the remaining calf's head broth.
Add lobster meat, oysters, Madeira, and mushrooms or mushroom ketchup.
Let it simmer for 30 minutes, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides gelatinous body and texture to the soup once simmered.
- Veal
- Adds rich meaty flavour and gelatin to the long-stewed broth.
- Beef
- Deepens the broth's savoury flavour during the long, gentle stew.
- Oysters
- Add briny, savoury seafood flavour to the finished soup.
- Madeira
- Adds sweetness and aromatic depth to the finished soup.
The step that matters
Stew gently, without a rolling boil. Gentle heat over several hours lets collagen in the head and veal break down into gelatin and keeps the broth clear. A hard boil makes it cloudy and can toughen the meat.
Swap the white pepper
