In a medium bowl, combine 2 eggs, milk, flour and salt and mix together to make a soft dough. Roll out thinly enough to make about twelve 10cm squares.
Bring a large pot of slightly salted water to the boil.
In a medium bowl, combine cottage cheese, 2 eggs and salt. Mix together and fill dough squares with cottage cheese mixture. Pinch sides together to seal and drop in boiling water. Cook for about 8 to 10 minutes or until the squares rise to the water's surface.
This is a great recipe! My family loves pierogis and this recipe makes it easy. I use a potato and cheddar cheese filling instead of the cottage cheese since that's how we've always had them. I've made double batches and frozen half, but the dough isn't the same once it's been frozen. - 08 Oct 2008
This made very delicious pierogis but I found the dough difficult to work with. I would imagine a kitchen aid mixer with a dough attachment would make this a breeze. - 08 Oct 2008
