I was playing the Sims Medieval the other day, and at one point, the blacksmith proves s/he's a capable cook by... taking a piece of meat, firing up the forge, and hammering the thing into a steak.
It's obviously done tongue-in-cheek, but it got me thinking - is it somehow possible to use a forge (bellows, coal, anvil, the works) to produce something actually edible?
If 'yes', what sort of constraints (e.g. necessary preparations, limitations on what kind of foods you could prepare) would there be?
Putting aside issues of cost and practicality.
