Food does not burn in the Sun Oven solar oven because it cooks evenly with a moist heat. This non drying heat prevents the food from burning. This is due to the fact that the temperature in the oven is consistent throughout the oven.
Air flow is important in the Sun Oven. Never place a pot or pan directly on the bottom of the oven. Always use the leveling tray or one of the dehydrator racks to set pots and pans on so that there is proper air flow.
