Ingredients
Directions
Prepare the head
Scald the calf's head with the skin on.
Remove the horny part.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides gelatin and body, giving the soup its rich, thick texture.
- Calf's foot
- Adds gelatin, which thickens the broth and gives it a silky mouthfeel.
- Beef
- Contributes savory meaty flavor to the broth during long, gentle stewing.
- Egg yolks
- Thicken the soup when gently heated, adding richness and smoothness.
- Flour
- Thickens the mixture added to the soup, giving body to the liquid.
- Madeira wine
- Adds sweetness and aromatic depth to the finished soup.
The step that matters
Stir the egg yolk mixture over gentle heat. Egg yolks thicken by coagulating when heated gently. If the mixture gets too hot or boils, the yolks can scramble and curdle, leaving the soup grainy instead of smooth.
Swap the clove
How well each one fits the dish's main ingredients (beef, ham, onion, carrot, turnip, celery, pepper):
- Parsleyfits better
- Thymefits better
- Marjoramfits better
- Clovethe original
Fit is the average pairing score against beef, ham, onion, carrot, turnip, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
