Add the onion, carrot, turnip, and bouquet garni.
Cover with water and simmer for several hours until tender.
Remove the head, strain the broth, and chop the meat finely.

Return the meat to the broth, add lemon juice, salt, and pepper.
Stir in cream, Worcestershire sauce, and sherry before serving.

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 give the soup its rich texture.
- Cream
- Adds fat and smoothness, softening the broth's flavour and giving it a rounder body.
- Lemon
- Adds acidity that brightens the rich broth and balances its fattiness.
- Sherry
- Adds aromatic depth and a touch of sweetness and acidity to the finished soup.
The step that matters
Simmering the calf's head until tender. The head must cook long enough for collagen and connective tissue to break down into gelatin, which gives the broth body and makes the meat tender. Stopping early leaves it tough and the broth thin.
Swap the lemon
