Directions
Prepare the head
Scald the calf's head with the skin on.
Remove the horny part from the calf's head.
Cut the calf's head into 2-inch square pieces.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Supplies gelatinous connective tissue that gives the finished soup body and a rich mouthfeel.
- Beef
- Adds savoury meaty depth to the broth during the long gentle stew.
- Calf's foot
- Releases gelatin into the broth, adding body and a silky texture.
- Flour
- Thickens the broth as its starch swells with heat.
- Egg yolks
- Enrich and further thicken the soup, adding richness and smoothness when gently heated.
- Sherry wine
- Adds acidity and aromatic depth to the finished soup.
The step that matters
Stir over gentle heat until nearly boiling. Egg yolks thicken by coagulating when heated; if the soup boils after they are added, they can curdle and turn grainy, so heat must stay gentle.
Swap the clove
How well each one fits the dish's main ingredients (beef, ham, onion, turnip, carrot, celery, pepper):
- Parsleyfits better
- Thymefits better
- Marjoramfits better
- Clovethe original
Fit is the average pairing score against beef, ham, onion, turnip, carrot, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
