What each ingredient does

Sheep’s head broth
Forms the liquid base and carries the main savoury flavour of the soup.
Leeks
Soften during simmering and add a mild, sweet onion-like flavour and tender texture.
Oatmeal
Its starch swells in the hot broth, thickening the soup and giving it body.

The step that matters

Simmer the leeks until quite tender. Leeks need a long, gentle simmer to soften fully. Stopping early leaves them fibrous and chewy, while a hard, rapid boil can break them apart and cloud the broth.
