This leg of lamb recipe from the American Lamb Board is an excellent way to grill up a leg of lamb without a rotisserie and without having to worry about drying out the lamb before the center gets cooked. Typically a boneless leg of lamb is already butterflied, but you want to make sure that it has a uniform thickness, so it will cook evenly.

  • 1 teaspoon ground cardamom, or ground ginger

  • 1/2 cup (120 milliliters) Dijon mustard
