Cobb Cobblestones are a smoke-free barbecue fuel designed for quick lighting, long burning, and minimal smoke, making them well suited to a fast evening barbecue or weekend entertaining. Unlike bulky bags of charcoal, the small stones store easily in a cupboard or garage shelf until needed. Each stone provides cooking heat in a Cobb BBQ for two whole hours, and the fuel heats up in minutes—there is no need for firelighters, and the cobblestones are smoke-free after the first 2 minutes and ready to cook in just 7 minutes. They burn hotter than ordinary charcoal and are made from a combination of coconut shell, charcoal, and corn starch, using waste products that would otherwise be thrown out. While designed for use with Cobb’s own barbecues, these cobblestones are also suitable for any small barbecue. - Product dimensions: 13cm (5") Dia. - Pack of 6.
