Campfire Cafe is a television show about campfire cooking. Lots of information on their website including recipes, tips and podcasts.
If you really want to do it right, you need to learn about different firewoods, cooking gear, cast iron pots, and accessories that will make the job easier and the cooking experience successful. There are weather conditions that will have a direct impact on cooking time, like wind. You’ll need to learn how to maintain your equipment, as well as the fire itself. A cook fire is not a blazing bonfire and learning to control the heat is key to successful open fire cooking.
The show’s companion book Over the Open Fire looks interesting.
