Ingredients
Directions
Prepare the head

Let the soup simmer gently for two hours.
Skim the soup clear and serve.
Make the brain balls
Pour hot water over the brains in a stew pan.

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 gelatinous meat and body that gives the soup its rich, thick texture.
- Butter
- Fat that carries flavour and browns the aromatics, adding richness to the soup.
- Leeks
- Aromatic base that softens during frying and adds a mild, savoury sweetness.
- Madeira wine
- Adds acidity and fortified sweetness that deepens the soup's flavour.
- Brains
- Soft, creamy meat that, bound with egg and flour, forms delicate dumplings.
- Egg (in the method)
- Binds the chopped brains so they hold together as balls in the soup.
The step that matters
Simmer gently and skim the soup. A hard boil makes the soup cloudy and can toughen the meat, so keep it at a gentle simmer and skim off foam to keep it clear.
Swap the leek
How well each one fits the dish's main ingredients (ham, parsley, thyme, clove, pepper, butter, madeira wine):
- Shallotfits better
- Carrotfits better
- Leekthe original
- Turnipfits about as well
