The designer states that the curved shape of the cooker is more stable than typical panel cookers in windy conditions. For best results, the cooker is meant to be used with a dark pot with a glass cover, to reach temperatures of 150°C to 190°C (300°F to 375°F). An oven bag can be used around pan in cold weather. The panels can also be laid flat for use as place mats. Sit a lantern inside to reflect more light at night.
