I got this recipe out of the Paula Deen magazine, March/April 2008 issue. Made it for myself for my birthday, and everyone REALLY loved it. It is a dense, extremely moist cake. It didn't last long at all when I broke it out. For me, I would say it could stand a bit more tangerine flavor, but it was quite good. I wonder if adding orange extract to the batter would make a difference? Maybe next time. . . I also think you could substitute any other kind of citrus, equal amounts, with the same delicious results.
