Heat buildup can cause a fire

Stay with the oven when microwaving popcorn, for heat buildup can cause a fire. Time heating per instructions but lean toward the shorter time (some ovens can scorch popcorn in two minutes).Food cooked in a microwave oven is as safe, and has the same nutrient value, as food cooked in a conventional oven. The main difference between these two methods of cooking is that microwave energy penetrates deeper into the food and reduces the time for heat to be conducted throughout the food, thus reducing the overall cooking time.
