These Polish treats came about almost by accident, I had half a package of wonton wrappers to use up from a pervious cooking project and some leftover mashed potatoes. While I wouldn't ordinarily use the wrappers for pierogis since the dough is a little bit different, they did work to use them up. And made them really simple to make.
24 round wonton wrappers
1 c. leftover mashed potatoes
2 Tbsp. butter
2 large onions
Salt and pepper to taste
Oil to fry in
Sour cream to serve
Using the butter, caramelize the onions using this method. In a bowl combine the mashed potatoes, caramelized onions, and salt and pepper to taste.
Start a large pot of salted water boiling.
Lay out 6 of the wonton wrappers. Leave the remaining covered, they dry out quickly. Top with a teaspoon of the potato mixture. With your finger, wet half of the wrapper and fold in half. Press to seal and set aside.
Repeat with remaining wrappers. After they are sealed it is ok if they dry out a little.
Place 8 wontons in the water at a time. Only boil for 2 - 3 minutes and remove from the water. Remove them just as they are about to float. Allow to dry slightly as you cook the remaining pierogis. IF they are soggy they wont fry properly.
Once all the pierogis are boiled heat the oil or butter in a large skillet. Once the oil is popping add the pierogis and cook until browned , flip over and cook until browned on both sides. Remove from the pan and repeat with remaining pierogis.
Serve with sour cream on top.
