I have frequent need of pork stock in my cooking, and it's not often available on the store shelves. Sometimes, as an afterthought to crock-cooking a large piece of pork, I make my own, by simply covering any bones left after deboning the pork with water, and cooking all of the meat off. This can yield significant amounts of broth, but is somewhat haphazard in terms of the flavor and amount.
Olive loaf has always been one of my favorite sandwich meats. While I was growing up, it was an expensive treat, only to be had once in a great while.
