Tiritli

Tiritli are traditional Croatian cookies originating from Slavonski Brod. They're made with a combination of flour, butter, sugar, egg yolks, sour cream, and a filling of walnuts, poppy seeds, or homemade fruit jams. The dough is rolled, then cut into rectangles. Each rectangle is topped with a dollop of the filling and the sides are then twisted and placed on top of the filling so that it remains on the inside. Once baked, these cookies are dusted with icing sugar. One of the earliest recipes for tiritli can be found in local newspapers from 1937.
