What each ingredient does
- Leeks
- Break down during long simmering to thicken the broth and add mild onion flavour.
- Old fowl
- Releases gelatin and flavour into the stock during long, gentle simmering, giving body to the soup.
- Stock
- Forms the liquid base that carries the flavour and cooks the leeks and fowl.
The step that matters
Simmer gently. A gentle simmer keeps the fowl tender and the broth clear. A hard boil toughens the meat and breaks the broth into a cloudy, greasy liquid.
