Here is a picture of a kettle simmering away at our camp. Cast iron kettles are expensive and heavy, and the American brands tend to look conspicuously modern. The African potjie style is said to be essentially unchanged from the 16th Century, when Dutch settlers introduced it to Africa. ("Potjie" is actually pronounced "poi-kei." Don't ask me why.) For a while they were available for half the cost of Lodge brand pots, but clever marketing has raised the price to be equal or even higher.
The iron jambalaya pot looks very old-fashioned, and can be had for less money. But, cast iron pots last practically forever, so a little difference in the price evens out over time.
I'm not sure which one we will end up with.
Of course, not every meal has to be roasted on a spit or simmered in a cauldron. Often, some cheese, bread, and fruit is plenty. I'm quite sure that, in the middle ages, cooking in the castle was fancier than cooking in the field. So, don't knock yourself out by confusing the two!
