Elko is a town in Nevada. This is from the Born to Grill cookbook. "Around the turn of the twentieth century, Basque immigrants from the Pyrenees brought their sheephearding skills and food customs to the high country of Idaho, Nevada, and California. The shepherds are usually with their flocks, but occasionally come into towns like Elko for a few days of frolic and feasting. Local boarding houses cater to their tastes with bounteous preparations such as this leg of lamb. Most people roast their lamb leg, but it;s also wonderful grilled if you butterfly the meat to reduce its thickness." There is at least a 4 hour marination not put in the cooking time.
