  3. Cut the meat from the head into neat square pieces and add to the soup.

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 meat and gelatinous body that gives the soup its substance.
Butter
Carries the browning of the aromatics and adds richness to the soup.
Madeira wine
Adds sweetness and depth of flavour as it reduces in the simmering soup.
Leeks
Build a mild, sweet aromatic base when fried with the ham and butter.
Fat ham
Adds savoury, smoky fat that browns and flavours the base.
Brains
Bind with egg and flour to form soft balls that add richness and body.

The step that matters

Simmer gently and skim. A gentle simmer keeps the broth clear, while a rolling boil emulsifies fat and cloudy proteins into it. Skimming removes the scum that rises, so the soup stays clean-flavoured.

Swap the leek
