We saw this being made on one of our favourite cooking shows. It's a Canadian show and everything is done on the barbecue. We tried it our for our Canada Day celebration and everyone loved it! You need to be able to grill using indirect heat. We used a 7lb bone-in leg of lamb and apple wood chips. It was grilled for about 6 1/2 hours, my husband says he could have done for another half hour and made it really tender. It was done and tasted great as it was. He used smoke pouches and everytime he changed it, he brushed the lamb with the leftover marinade. We will definately be making this again. I hope you enjoy it as much as we did.
