The Most Versatile Backup Stove In The World Allows You To Cook Anything, Any Time, Any Where. The Crisis Cooker is a highly efficient charcoal, wood or propane cooker that allows you to boil, grill, fry or bake using a fraction of the fuel that other systems use. You can cook an entire meal with as little as 6 briquettes (even a Thanksgiving turkey dinner can be cooked with only 12!) – less than one tenth of the fuel you would use on a conventional charcoal grill and far less than you would use in a wood cook stove.
