Kroštule are traditional Croatian pastries originating from the regions of Istria and Dalmatia. They are made by deep-frying ribbon-shaped dough. The dough consists of flour, sugar, egg yolks, oil, and milk. It is traditionally flavored with lemon zest, limoncello, or orange liqueur.

Kroštule are sprinkled with powdered sugar while they are still warm. Nowadays, these deep-fried pastries are typically associated with the festive carnival season.
