Perhaps the densest dessert ever concocted by man, gibanica - more specifically Prekmurska Gibanica - is also one of the tastiest. Consisting of layer after layer of poppy seeds, walnuts, apples, raisins and cottage cheese fillings separated by flaky dough, the cake has been served on special occasions in the Prekmurje region of Slovenia for centuries, and has long had the status of a national speciality. On 4 March 2010, Prekmurska Gibanica was given Traditional Speciality Guaranteed status by the EU, meaning that anyone wishing to use the TSG label on their gibanica must follow precise specifications when preparing it. If you can't make it to Prekmurje to sample the most authentic stuff, you can usually find it on the menu at traditional Slovene restaurants in Ljubljana.
