I bake them all the time on a pizza stone on the grilling grid, 375-400 for an hour or more. I just set them on the stone after washing nothing else, I check them every now and again and turn them when they are getting black on the bottom. they are done when they start to ooze sweet caramelized goodness out of the end. The skin will most likely be black and even look burnt but the inside will be oh so good and all you will need is just a little butter.
