Yesterday, I repostitioned the roaster solar cooker after lunch and then went shopping.
I had put a 3 qt pot in that morning with 2 qts of water to see how hot I could get it. I dumped the most of the hot water on some weeds in the front yard, left 1/4 cup and put a lone chicken breast in with skin side up.
I got home to see the chicken golden brown! I quickly snapped this shot... before rushing in to devour the chicken... sorry... didn't take time to see how bad this shot was before eating the chicken.
The lesson I'm learning the hard way: leave the lid on and don't mess with it to check temps. I lost about 20 F just by removing the domed lid to the roaster.
