The design of the Cobb™ portable cooker originated with safety in mind. An innovation straight out of Africa, the Cobb was initially designed as a cooking system for people in rural areas, without access to electricity so they could cook in a safer environment, with less danger of out of control fires. The first proto type of the Cobb cooker was a ceramic sphere-shaped device that cooked well, but was heavy and cumbersome. The initial fuel source for the Cobb was dry corn cobs, abundant in rural Africa, hence the grill’s name. The unit has been refined over and over, and the result is a small, eco-friendly, portable and incredibly efficient portable cooker. Compressed charcoal briquettes or Cobble Stones have replaced the corn cobs.
