Food / Kudłate Pierogi [5]

My father has always raved about pierogis my grandmother used to make, Kudłate pierogi. In english, we always called them fuzzy pierogis. She stopped making them before I was born because they were too much work but were my dad's favorite. I have tried to find them at polish restaurants or in recipes online but can't find anything feasible. A few recipes come up but the translations don't make sense. If anyone had a recipe or could point me to a cookbook that has a recipe, that would be great. Thank you!
