With cold weather, comes daily fires in the woodstove, cheerily keeping my little house toasty warm. Sometimes, I take advantage of the heat to cook a meal or two. Recently, I tried baking potatoes in my cast iron dutch oven, a vintage find at a garage sale years ago. First, I washed, pricked and wrapped my potatoes in foil and placed them into the pot.
I've found it works best to diffuse the heat a little, otherwise things boil far too quickly (or bake, in this case). Using canning rings makes a useful trivet.
And then, it's a matter of plonking the dutch oven onto the stove, stoking the fire, and allowing your whatever-it-is to cook until done. I left the potatoes for a few hours, and they came out perfectly!
