Why it works: Clove and allspice match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 7,874 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Calf's-head Soup
Ingredients
Directions
Prepare the head
Cleanse the calf's head thoroughly and boil it in 7 quarts of water until the bones can be removed.
Make the soup
Brown 2 tablespoons of flour in another pot, then strain the broth from the head into it.
Add 2 large onions, a few cloves, powdered allspice, pepper, and coarse sea salt to the pot and bring to a boil.
After about an hour, cut the head into small pieces and add it to the pot.
Pick out the brains, beat them with flour, butter, and chopped parsley to thicken the soup.
Boil for one hour after adding the head, then add the force meat balls and 2 finely chopped hard boiled eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides the meat and gelatinous body of the soup.
- Flour
- Browned and later mixed with brains and butter to thicken the soup.
- Brains (in the method)
- Beaten with flour and butter to enrich and thicken the soup.
- Butter
- Adds richness and helps bind the thickened brain mixture into the soup.
- Hard boiled eggs
- Chopped and added at the end to give body and texture to the soup.
The step that matters
Thickening with brains, flour and butter. Beating the brains with flour and butter before they meet hot broth helps them blend smoothly; added too hot or unmixed, the flour clumps and the soup stays thin or lumpy.
Swap the onion
How well each one fits the dish's main ingredients (flour, clove, allspice, pepper, butter, parsley, meat):
- Shallotfits better
- Carrotfits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against flour, clove, allspice, pepper, butter, parsley, meat. Candidates are from the same food group and used in at least 100 recipes.
