Why heat the kitchen and use electricity when the sun is willing to do the work for you? Our grown sons love to use the solar oven. They also make their own beer, which is why this is their favorite recipe using the Sun Oven:Put a chopped onion and a bottle of home brew into a covered casserole or dark covered pot and heat until the onion is cooked. Add 5-6 beer bratwurst and cook until done.
