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 gelatine that give the soup its body and richness.
Butter
Adds fat for richness and browning of the aromatics at the start.
Brains
Bound with egg and flour, they form soft, tender forcemeat balls.
Egg
Binds the chopped brains so the forcemeat balls hold their shape.
Leeks
Add sweet, mild aromatic flavour to the soup base.
Madeira wine
Adds acidity and rich, fortified sweetness that deepens the broth's flavour.

The step that matters

Skim the soup clear. Skimming removes fat and coagulated proteins that rise during simmering, keeping the broth clear and clean-tasting rather than cloudy and greasy.

Swap the leek
