I won't lie, this recipe is a lot of work, high in fat and high in calories. It will take a couple hours to make and I only do it once year on my husband's birthday. All that said, it is so worth it. If you want to break you diet this is the one to do it with. My mother says she got the recipe when my father was stationed in Germany in the 70's. I don't think she even remembers the original source any longer. Of note: I have never used the chicken livers, but the original recipe does call for them. Plum tomatoes are difficult to find these days and you can substitute any canned tomato you like.
