Spin me right round
There really is no other cooking method which matches food cooked on a rotisserie on a grill - the spinning motion allows the outside of the food to have the maximum exposure to heat, and so gets ultra crispy. The rotation also makes the meat self baste, as moisture and juices are unable to run off and are absorbed back into the meat. The result is perfectly cooked chickens, turkeys, rib roasts, the list goes on.
But rotisserie doesn't just mean whole birds or large joints: Weber® have produced add ons such as the basket, fine mesh basket and skewer system which allow you to create crispy fries, popcorn or mountains of chicken wings, all on your Weber® gas grill.
