Cock-a-Leekie

Ingredients

• 1 capon or large fowl
• 2–3 bunches leeks, fine
• 5 quarts stock
• to taste pepper
• to taste salt

Method

Cock-a-Leekie is fundamentally a braising technique dressed as soup: the bird steams in its own stock whilst the leeks break down into a silken thickener. This isn't a broth you strain clear — the leeks dissolve into the cooking liquid and give you body without flour or beurre manié.

Prepare the leeks first. Split them lengthways and wash between the layers to clear grit, then slice into 1-inch rounds. Older leeks — the ones with a thick white and pale green — benefit from blanching in salted boiling water for 3–4 minutes to soften them and remove the sulphurous edge; younger spring leeks skip this. Truss the capon or large fowl tightly so it holds its shape during the long simmer — legs tucked, wings folded. This matters for carving later.

Bring the stock to a steady simmer in a pot large enough to hold the bird comfortably submerged. Lower in the fowl and half the leeks, then reduce heat so you see only the occasional bubble breaking the surface — not a rolling boil, which toughens the meat through violent agitation. After 30 minutes, add the remaining leeks. The staggered addition means the first batch breaks down completely into the liquid, whilst the second batch stays intact enough to read as vegetable. Skim the surface every 15 minutes for the first hour to remove coagulated protein and scum; the broth should turn from murky grey to translucent amber. The total time is 3–4 hours depending on the bird's age and size — the meat should come from the bone with almost no resistance, and the thigh juice should run clear.

Remove the fowl to a board and let it cool slightly. Carve the meat into neat pieces, discarding the skin unless you like it (traditional versions do). Check the stock-based soup for seasoning — it should taste as much of leek as poultry — and adjust salt and pepper. Place the carved meat into a tureen, pour the hot soup and its softened leeks over it, and serve. The leeks do the thickening work; the broth clings to them in an emulsion that feels substantial without heaviness.
