Dutch Oven cookery

Thanks for the links, Gordon. I'd already found Byron's site.
The set my son and wife have is the type with the lipped lid for piling coals on top of. I haven't yet bought or shopped for any myself.
I did notice on the site that I visited that cooking with charcoal bricquets was described, as you do to. I see the practicality of this, but now am wondering about the "purity" of this method at the campsite. Typical retrohead thinking process! I think we'll bring bricquets along next time as a campfire "supplement".
