You can make these in the oven and/or gas grill too using the highest heat settings but the campfire method is the traditional one. I have been making these babies for over 45 years -- I was raised in a log cabin and we made them in the fireplace coals all the time. The flavor is heavenly. This is a LOT of fun for the kids and, closely supervised, (and given a little assistance), they can make their own. Enjoy.
