The pizza box solar oven can reach temperatures of 275 degrees Fahrenheit, hot enough to cook food and to kill germs in water. A general rule for cooking in a solar oven is to get the food in early and don’t worry about overcooking. Solar cookers can be used for six months of the year in northern climates and year-round in tropical locations. Expect the cooking time to take about twice as long as conventional methods and allow one half hour for preheating. You may want to try making s'mores (graham crackers with melted marshmallows and chocolate) or English muffin pizzas, or something that you can eat even when it’s raw!
