Those videos are amazing and mouth watering. I have trouble keeping a hot dog or hamburger from burning on a grill let alone cook something over an open fire. I'm pretty good at marshmallows though.
Loved the steak king video, did he say "fake" beef fillets? Was that real steak or a vegetarian product? Anyhoo, looked yummy and so healthy too! We've made quite a few rib eye steaks on an open fire while camping, using a metal grate though usually balanced on some rocks around the edges, the kind that come with small barbeque grills.
