Strukli are made in the Zagreb region. Maybe here they have a unique flavor or they're eaten more frequently, but these little "ravioli" with cheese or apples, tossed with breadcrumbs, have taken the whole country by storm.

In the northern regions of the country, delicious strukli are served at Christmas with a compote of dried fruits (prunes, apples and pears).

1. Combine the flour and salt with a little warm water. Let rest 30 minutes.
2. Meanwhile, beat the egg whites to stiff peaks, then add the yolks, fresh cheese and sour cream.
3. Roll the dough out into two equal rectangles about 3-4 mm (1/8") thick..
4. Divide the filling over one rectangle, placing 1 large tbsp. every 10 cm (4") or so.
5. Cover with the second rectangle of dough. Cut the strukli with a knife or cookie cutter as you would ravioli. Seal the edges by pressing with a fork.
6. Drop into boiling salted water and cook for 15 minutes. Remove with a slotted spoon once they begin to float.
7. Meanwhile, melt some butter in a skillet over moderate heat; add the breadcrumbs and sauté them in the butter until golden.
8. Sprinkle the strukli with the breadcrumbs and serve hot.
