Thanks to Chef Queen of Cups for posting a lower-fat version of this recipe. Here is the original...low-fat it is not (!), but to me, it is the ultimate comfort food. It gets its name from the strong Southern tradition of bringing a covered dish to families in mourning (with a double meaning resulting from the saturated fat content!) --this was the favorite of all the comfort foods brought on one such occasion. It's from the book "God Save the Sweet Potato Queens" by Jill Conner Browne.
