Season and roast

  1. Season the shoulder of lamb with butter, flour, and coarse sea salt.

  2. Roast the lamb for 20 minutes.

  3. Baste the lamb occasionally during roasting.

Serve

  1. Garnish with watercress before serving.

What each ingredient does

Lamb shoulder
Forms the main body of the dish, providing the meat that is roasted and served.
Butter
Adds fat that carries flavour and helps the surface brown and stay moist during roasting.
Flour
Helps the seasoning coat the surface and encourages browning on the outside of the meat.

The step that matters

Baste the lamb occasionally during roasting. Spooning the fat and juices over the meat keeps the surface from drying out and helps it brown evenly, while the interior cooks gently.
