Nut roll, Also known as Kolachi. 

The nutroll or Kolachi has a history of being a traditional Slovenian, Croatian and Serbian pastry, is made from buttery pastry dough rolled into thin layers and filled with a walnut paste.   Each loaf contains a half pound of nut roll paste.  

We are told not many make them with the same quality and care, and this is one of our most requested and  shipped items during holidays. 

It measures 12" long.
