Traditionally prepared in western Slovenia, namely the town of Idrija, this popular pasta dish can be described as a variety of ravioli. Žlikrofi are made with two layers of thin pasta dough wrapped around the filling, and apart from their charming shape resembling a bicorne hat, their authentic potato filling is even more distinctive.
Ever since the first references to this delicious Slovenian dish, except for the variations in the filling, the recipe hasn't significantly changed over the years. The oldest written source is found in a 1936 book Naš Idrijski Kot, in which the author describes how the popular žlikrofi were prepared only on special occasions when they were typically filled with potatoes, meat, or turnip mash.
