Logan and I finally finished making our solar cooker. It is a box cooker from the book Cooking With Sunshine. It was pretty easy to make, it is basically 1 box inside another box with crumbled newspaper as insulation. We painted the outer box black and covered the inner box with foil. Logan had a lot of fun painting the glue onto the box, smoothing the foil down, and then painting the outer box black.
We cooked for the first time in it yesterday. Here is the completed cooker with the pot in it. We made white rice for our first attempt since it is easy and cooks relatively quickly.
We left the pot outside for 4 hours and viola, rice! It tasted great and was so much fun. I highly recommend the book Cooking With Sunshine. It has easy to follow directions and a ton of great looking recipes. I look forward to playing with this more as the summer goes on.
