German Mennonite-style perogies - the flour and cottage cheese measurements in this recipe aren't exact. You'll find in a lot of mennonite cooking there aren't exact measurements since it's done a lot by look and consistency.
Combine all of the dough ingredients together to make a soft dough. Roll out thinly onto a floured board and cut into circles (I like to use a mason jar lid). Blend the filling mixture well and put enough filling to cover half of the circle but leave edges to seal the wareneki. Fold the other half over into a half moon shape then press the edges together with fingers or lightly with a fork. Boil the wareneki for about ten minutes - they will float when cooked. Serve with gravy or butter or after they're boiled you can fry the wareneki with onions and bacon and serve with sour cream (I like mine with ketchup).
