Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Boiled Calf Head
Ingredients
Directions
Prepare
Thoroughly clean the calf's head and remove the brains.
Soak the head in warm water to blanch it.
Soak the brains in warm water for about an hour.
Place the head in a stewpan and cover with cold water.
Boil
When it boils, add salt and remove any scum that rises.
Boil the head until perfectly tender.
Boil the brains, chop them, and mix with melted butter, minced parsley, pepper, salt, and lemon juice.
Serve
Remove the head, skin the tongue, and place it on a dish with the chopped brains around it.
Garnish with parsley and melted butter, and serve the remainder in a tureen.

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 body of the dish, becoming tender and rich through long simmering.
- Brains (in the method)
- Provide a soft, creamy texture when boiled, chopped, and mixed with butter.
- Melted butter
- Adds richness and moisture to the chopped brains and the finished garnish.
- Lemon juice
- Adds acidity that brightens the rich butter and brains.
The step that matters
Skimming scum after adding salt. Scum rising from the head contains coagulated proteins and impurities; removing it as it forms keeps the broth clear and the flavour clean.
