I love the sound of this Trifle. I live in the South, and when I was growing up, Gingerbread was served frequently and was always topped with lemon sauce or served with lemon sauce on the side (although never, for some reason, as a cake with lemon frosting). So I have always thought of the two flavors as going together -- part of the fun of Recipe Swap is how it has expanded our ability to "share recipes over the back fence!"
