Slow Roast Shoulder of Lamb with Fresh Mint Sauce & Roasting Juices

Although this dish works well with any well sourced lamb, salt marsh lamb is without a doubt the best. The seawater-washed pasture doesn’t make the meat saltier but sweeter, and the salt tolerant plants that they graze on, such as samphire and sea purslane, give the meat a unique taste. Because they roam and use their muscles the meat is lean and dark with bags of flavour.

The first step is to marinate the lamb with rosemary, garlic and anchovy; this will give the meat an added boost of umami, making it mouth wateringly delicious. The next day, roast it in low oven, on a bed of roughly cut vegetables; this stops the bottom of the joint from searing on the roasting tray, keeping it soft and tender. A large cup of water in the tray keeps the oven moist and will later become the sauce.

When it comes to mint sauce fresh is definitely best. Pre-made mint sauce may have the sharpness to cut through rich lamb but it lacks the pungent aromatic flavour of freshly cut mint. I make my mint sauce with balsamic vinegar, as it gives a more rounded, earthy flavour.
