I finally tried the solar cooker today. I’d been waiting to find the perfect pot in one of the thrift stores (Cooking with Sunshine recommends thin black enamel cookware). Nothing has turned up yet, so I just went for it with my grandma’s heavy cast iron pot.
I put the quinoa in the cooker at 10 am, and pointed it at the sun. The thermometer read about 200 f. Nathen re-aimed it once or twice while I was at work. At 5 pm I pulled the pot out and the quinoa was starting to burn at the edges.
I think I used too much water and the quinoa was a little mushy - tho if I’d used less it probably would have been more burnt.
Clearly we have some refining to do, but this awesome cooking power is great news, as using the stove inside the trailer during the day is pretty unappealing.
