Calfs Head
Ingredients
Directions
Prepare the head
Boil the calf's head in water for 5 minutes to remove hair.
Scrape off the hair from the head.
Soak the cleaned head in cold water for 24 hours in winter or 10 hours in summer, changing the water 2–3 times.
Place the head in a saucepan covered with cold water and add salt, onion, lemon, parsley, thyme, bay leaf, cloves, garlic, peppercorns, and vinegar.
Boil gently until cooked through.
If boned, remove the brain and soak it in cold water.
Make the sauce
Melt butter in a saucepan and add flour to it.
Stir until the mixture turns yellow.
Gradually add broth, stirring until thickened.
Add the diced calf's head to the sauce.
Bring the mixture to a boil.
Remove the sauce from heat.
Stir in egg yolk and chopped parsley.
Bring the sauce to a second boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Forms the main meat, which becomes tender through long gentle simmering.
- Butter
- Carries the flour and gives the sauce its rich flavour and smooth mouthfeel.
- Flour
- Thickens the butter and broth into a sauce as its starch swells with heat.
- Broth
- Forms the liquid of the sauce, adding savoury flavour as it thickens.
- Egg yolk
- Enriches and thickens the sauce, adding richness and body when stirred in off the heat.
The step that matters
Stirring in the egg yolk off the heat. Egg yolk thickens by gentle heat; if the sauce is too hot or boils after it is added, the yolk can scramble and turn grainy, so the sauce must be removed from heat first.
Swap the clove
How well each one fits the dish's main ingredients (onion, lemon, parsley, thyme, garlic, vinegar, butter):
- Marjoramfits better
- Tarragonfits better
- Sagefits better
- Clovethe original
Fit is the average pairing score against onion, lemon, parsley, thyme, garlic, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
