Hmm... I don't know what those things are that Larry made, but they sound fantastic!! When my family makes klatskis they are like little filled pockets- like a Lithuanian version of ravioli. Here is our dough recipe.
2 cups flour
2 tablespoons oil
about 1/4 milk
I make it in the food processor and add about half the milk at a time and only add enough to just bind the dough. Process until it comes into a ball and then roll out in little pieces. During the year we fill them with just about anything chopped up, but at Christmas we use farmer's cheese and mushroom.
Hope this helps!
