Reddit mentions of Cooking with Fire: From Roasting on a Spit to Baking in a Tannur, Rediscovered Techniques and Recipes That Capture the Flavors of Wood-Fired Cooking

This was my first time doing anything like this. It was really fun and I learned a lot. I followed the general guidelines from the Cooking with Fire cookbook. Greenwood spit made from a branch I pruned off a crab apple tree. Drilled two holes through it to skewer through the chicken. I was too nervous to burn the chicken so it took way longer than it needed to. Next time I'll be more aggressive with the coals. Although constant turning of the spit is unnecessary, somebody did need to hold the spit at all times. Next time I'll see if I can rig up something to hold the spit in place.

If you are interested enough to invest in a book, Cooking with Fire is a good general resource to get you started. My personal taste leans towards dutch ovens and potjies but those are both heavy to trek in if you are hiking and camping but if you are car camping or cooking on the beach or in your backyard those are both fantastic tools. Gonna be experimenting with open fire spit roasting this winter I think.
