Chef's tips

Salt marsh lamb has a clean, herbal sweetness that requires minimal seasoning. Always allow the meat to rest fully before carving to keep the joint juicy. Use the softened roasting onions and pan drippings with a little hot stock to create a light, natural gravy.

Ingredient substitutions

Gower salt marsh lamb leg → standard Welsh mountain lamb leg or shoulder
Halen Môn sea salt → any coarse flaky sea salt

Storage

Keep leftover carved lamb in an airtight container in the fridge for up to three days.

Reheating

Reheat slices gently in a covered ovenproof dish with a splash of gravy at 160°C (140°C fan) until piping hot.

Common mistakes to avoid

•Overcooking the lamb, which dries out the lean and tender salt marsh meat.
•Carving immediately without resting, causing tasty juices to run out onto the board.
•Using heavy spices that overpower the distinctive natural coastal flavour of the meat.

Serving suggestions
