Potica
Potica is a traditional festive pastry from Slovenia. The word potica as well as some regional names for potica, like povtica, potvica, etc. are descended from the word povitica. Povitica is derived from the verb 'poviti', which means to wrap in or to envelop, and it signifies a type of pastry that you roll. This type of dessert is common in many Eastern European countries as well as in regions bordering Slovenia, for example, in Friuli in neighboring Italy, they prepare a sweet bread called gubana, in Austria, a roll called Kärntner Reinling. Potica consists of a rolled pastry made of leavened paper-thin dough filled with any of a great variety of fillings, but most often with walnut filling.
