Well, good question what I would buy with the gift certificate if we won it? Mostly legumes and other delicacies that I can put in the solar oven. Solar cooked beans or lentils are the best beans we have ever eaten and they require minimal effort: add water, put in solar cooker, come back a few hours later, eat. solar cooking = smart slowfood with minimal effort. Solar cooked beets are superb. And just for the record, yes, I have been cooking for decades by now, but solar cooking only for a few months, which is hard to believe considering the abundance of sunshine In Hawai‘i...
