MMMM.... feeling very Ukrainian today.  Made my own perogie dough and filling from scratch.  Brings back some really good memories from when I was a wee little girl making (and eating) homemade perogies.

Perogie Dough

• 4 1/2 cups all-purpose flour
• 2 teaspoons salt
• 2 tablespoons butter, melted
• 2 cups sour cream
• 2 eggs
• 1 egg yolk
• 2 tablespoons vegetable oil

In a large bowl, stir together the flour and salt. In a separate bowl, whisk together the butter, sour cream, eggs, egg yolk and oil. Stir the wet ingredients into the flour until well blended. Cover the bowl with a towel, and let stand for 15 to 20 minutes. 

Separate the perogie dough into two balls. Roll out one piece at a time on a lightly floured surface until it is thin enough to work with, but not too thin so that it tears. Cut into circles using a cookie cutter, perogie cutter, or a glass. Brush a little water around the edges of the circles, and spoon some filling into the center. Fold the circles over into half-circles, and press to seal the edges. Place perogies on a cookie sheet, and freeze. Once frozen, transfer to freezer storage bags or containers. 

To cook perogies: Bring a large pot of lightly salted water to a boil. Drop perogies in one at a time. They are done when they float to the top. Do not boil too long, or they will be soggy! Remove with a slotted spoon.
