I just remembered something that I thought I'd add. When I was in college I got a cast-iron pot with a lid that was basically a Le Creuset pot without the enamel - except that it cost $10 and I got it from a camping store for cooking in a campfire. I don't know if Montreal-area camping stores would also have such a thing (Manitoba is more of a huntin' and fishin' kinda place than Montreal, or so I assume), but if they do, I bet anything it would work perfectly well for this recipe. It might be worth a try.
