Cooking over hardwood coals at a remote campsite in winter uses the same oven and the same math as summer — three legs, a flanged lid, and briquettes counted by the diameter of the oven. This page gathers the cold-weather-relevant basics already published on Clouds Over Trees.
A true campfire Dutch oven needs two critical features: three cast-iron legs on the bottom so it sits over hot coals without suffocating them, and a flanged (raised-lip) lid that holds charcoal briquettes on top without letting ash fall into your food when you lift the lid. The Lodge 6-Quart Camp Dutch Oven includes a heavy-duty steel bail handle for hanging from a campfire tripod and comes factory pre-seasoned, and its heavy wall thickness prevents hot spots when cooking over uneven hardwood embers.
One of the greatest perks of a flanged camp Dutch oven is the ability to bake cornbread, biscuits, or a peach cobbler right over wood coals. To hit a standard baking temperature of 350°F, take the diameter of your Dutch oven in inches and multiply it by 2: a 10-inch oven needs roughly 20 total briquettes (7 bottom, 13 top); a 12-inch oven needs roughly 24 (8 bottom, 16 top). Put about two-thirds on the lid. For roasting or baking at 400°F or 425°F, add 2 to 4 extra briquettes to the top lid.

Use warm water with a chainmail scrubber to strip burnt-on food and carbon buildup — machine-soldered 316 stainless steel rings with smooth, rounded edges glide right over polymerized oil seasoning. Full care guide: see Cast Iron Care on this site.
