my recipe for half leg of lamb. put tablespoon of dijon mustard, tablespoon of oil, tablespoon of redcurrant jelly, mix well together, get the lamb and score the skin all over, just cut into the skin and push inside a slice of garlic and a piece of fresh rosemary. get the redcurrant/oil/dijon mustard mix and rub all over the lamb, coat very well. put lamb in fridge overnight. when you want to cook it, it will take about 2 hours, won't come out pink, but cooked to perfection.
