Another great banana cake but with a blast of citrus; gives it an added zing! It is lower in fat than some and I quite often make it without the icing so it is not too sweet either. I often add something extra as well...often a handful of dried cranberries really sets it off. I usually bake it in a tube pan but that is my personal preference. This recipe originated in "Lighthearted Everyday Cooking" by Anne Lindsay.
