Make sure that the foil-covered flap is reflecting light into the pizza box, through the plastic-covered window. You should be checking periodically on your oven, to make sure it is in the sun. Reposition your solar oven when needed, so that it faces direct sunlight. You can rotate solid food every 10-15 minutes as well, so it cooks evenly. Stir liquids (if you're cooking something like fondue, rice, or soup) every 10 minutes. Here are a few tips for having success with your solar oven: Other recipes you may want to try are making baked potatoes, rice with vegetables, chocolate fondue, s'mores, and roasted apples with cinnamon and sugar.Įven on partly cloudy days, there may be enough heat and light from the sun to slow cook a special dish. You can also pre-heat your oven by setting it in direct sun for up to an hour. #Sun spotter with mirrors zip#
Putting solid food in a glass dish and liquids in a heavy plastic zip lock bag works well. If you do not want to wait long to have a solar-cooked dish, try heating up something that has already been cooked, like leftovers, or a can of soup. The internal temperature of our pizza box solar oven was 125° F. It took about 45 minutes for our cheese to melt and the tortilla to become soft. We made a cheese roll-up by melting cheese on a corn tortilla.
Although this method will take longer, it is very easy to use, and it is safe to leave alone while the energy from the sun cooks your food. Your solar oven can reach about 200° F on a sunny day and will take longer to heat things than a conventional oven. The black paper absorbs the heat at the bottom of the oven, and the newspaper makes sure that the heat stays where it is, instead of escaping out the sides of the oven. Once it has gone through the plastic wrap, it heats up the air that is trapped inside. The foil reflects the ray and bounces it directly into the opening of the box. How does it happen? Rays of light are coming to the earth at an angle. As it sits out in the sun, your oven eventually heats up enough to melt cheese, or cook food ! Ovens like this one are called collector boxes because they collect the sunlight inside. The heat from the sun is trapped inside of your pizza box solar oven, and it starts getting very hot.
To take food out of the oven, open up the lid of the pizza box, and using oven mitts or potholders, lift the glass dish out of the oven. Place the thermometer inside your oven before you close it, so you can check the temperature. So the paper at the bottom doesn't get dirty, put what you would like to cook on a clear plastic or glass plate. Cooking a hot dog or making nachos with chips and cheese are also fun treats to make in your solar oven! It would also work great to heat up leftovers. You can make toast by buttering a slice of bread then letting the sun do the rest. You may want to angle the entire box by using a rolled-up towel. Use a ruler to prop the flap at the right angle. Take it outside to a sunny spot and adjust the flap until the most sunlight possible is reflecting off the aluminum foil and onto the plastic-covered window. The best hours to set up your solar oven are when the sun is high overhead-from 11 am to 3 pm. The newspaper rolls should make it so that the lid can still close, but there is a seal inside of the box, so air cannot escape. It may be helpful to also tape the rolls closed first. Tape them down so that they form a border around the cooking area. To insulate your oven so it holds in more heat, roll up sheets of newspaper and place them on the bottom of the box. How much you need will depend on the size of the pizza box you're using to make your solar oven. The black surface is where your food will be set to cook. Line the bottom of the box with black construction paper -black absorbs heat. If you use a plastic bag, cut out a square big enough to cover the opening and tape one layer over the opening. Leave about an inch of plastic overlap around the sides and tape each side down securely, sealing out air. Do this by opening the box and taping a double layer of plastic wrap over the opening you made when you cut the flap in the lid. Use clear plastic wrap to create an airtight window for sunlight to enter the box. To do this, tightly wrap foil around the flap, then tape it to the back, or outer side of the flap. Cover the inner side of the flap with aluminum foil so that it will reflect rays from the sun. Fold this flap out so that it stands up when the box lid is closed. Cut along three sides, leaving about an inch between the sides of the flap and the edges of the lid. Use a box knife or sharp scissors to cut a flap in the lid of the pizza box.
