Stok Drum

At first glance, the Stok Drum looks like a typical charcoal grill, what with its dome top, tripod frame, and lid-mounted thermometer. But it one-ups other models with its modular system: The center of the 22.5-inch cast-iron grate pops up, and you can replace it with various inserts (from pizza stone to smoke infuser) that will enhance any barbecue.
