My husband told me that he saw one of our neighbors in a store recently and the neighbor asked, "What is all that STUFF in your front yard?"
He explained that they are solar cookers and ovens, but we have too many trees in the back yard to set them up there.
Today I baked a ginger bread in the roaster solar oven, then put my home made spaghetti sauce in there to cook. The panel cooker has a shallow dish with cubed beef for the pasta sauce.
No, I chickened out, and cooked the pasta indoors on the stove. I had frozen cheese stuffed ravioli that really needs a good rolling boil to cook without getting mushy.
