1. Preheat the oven to 400°F (200°C). Lightly coat a roasting pan with nonstick cooking spray. To make the double mint sauce, combine the mint jelly, lemon juice and fresh mint in a small saucepan. Stir constantly over medium heat until the jelly melts, about 5 minutes. Remove from the heat and set aside.
2. Meanwhile, cut the leg of lamb horizontally three-quarters through with a sharp knife. Open and spread flat like a book. Place the meat between two pieces of plastic wrap and pound with a meat mallet or rolling pin to about 2 cm thick.
3. Brush about 2 tablespoons double mint sauce on the lamb, and then sprinkle with the garlic, rosemary and pepper. Squeeze the juice from one lemon half over the lamb. Roll up the lamb from one wide side. Tie with kitchen string, in both directions. Transfer to a pan, seam side down. Squeeze the remaining lemon half over the lamb and pour on the wine or stock.
4. Roast for about 50 minutes, or until done to your taste. Let the meat stand for 10 minutes before slicing. Reheat the remaining sauce. Remove the strings from the lamb and cut the lamb into 1 cm slices. Serve leg of lamb with the double mint sauce.
