They are called Dutch ovens. I had planned to make a post out of explaining how they work, how we used them, and what you could do with them, but I found that website, and I know I couldn’t do any better. I would note that in the list of people he credits at the bottom of his site is his sister, who learned to cook in Dutch ovens through the Boy Scouts.
So go and take a look. A Dutch oven isn’t a backpacking item. It’s for cooking when you’re set up somewhere and you only have to unload it from the trailer. You can make anything you would make on the stove or in your home oven. We use them whenever we camp near the vehicles. It became competitive. Pizza, chili, stews, chicken and pastry, rolls, bread, baked chicken and potatoes, and then desserts. Cake, pie, cobbler, baked apples. In an iron pot with hot coals above and below.
We had one Asst. Scoutmaster that would stack them. The coals on the top of one served to heat the bottom of the next one. Stacks of three or four, two main dishes, breads, and a dessert. He prided himself on his skills and rightly so.
The Scouts picked up on what we were doing, and some years more than others, would use the ovens on campouts. If a Patrol of Scouts can do it, so can you. Lodge makes the heavy ovens, every outdoor supply center and website stocks them. Don’t settle
for hot dogs and canned beans. Buy or borrow a Dutch oven and make everyone you’re feeding think you really know what you’re doing.
Cooking is at once child’s play and adult joy. And cooking done with care is an act of love.
