It also includes variations from a few other folks that you might like to try.Roughly translated from Bavarian to German, this is Pflaumenkuchen, which, roughly translated from German to to English is Plum cake. However, Zwetschgen aren't ordinary plums, a Datschi isn't really a Kuchen, and a Kuchen is most definitely NOT a cake!This dessert is made of the slightly tart Italian plums, which are unfortunately only available at certain times of the year. Don't try to make it with ordinary plums; they're too sweet and too juicy.
