Our readers have bought thousands of Char-Griller’s Akorn Kamado grills over the past few years, and now, they can add the Char-Griller Smokin’ Stone to their setup for an all-time low $19. The stone absorbs moisture and directs heat around the perimeter of the grill, essentially turning it into a convection oven for slow smoking. Just remember to invite me over whenever you use it.
