Making broth is so easy to do, and the results are so wonderful and so almost infinitely useful, I really don't understand why it's almost disappeared from home cooking. Well, actually, I can guess: fewer and fewer people cook anything at all, let along things like homemade broth, which has an undeserved reputation for being difficult to make. Add to that the undeniable fact that broth takes time, something people seem to have less and less of. But, except for the first few minutes, broth can be left virtually unattended until it's done. I usually start the broth on a lazy Sunday afternoon and just let it simmer while I read a good book, watch a movie or do whatever else I feel like around the house. When it's done, just turn off the stove and leave it until you're ready to eat, then reheat.
