Cook 2 strips of bacon till crisp, SAVE DRIPPINGS,(i CUT MY STRIPS IN HALF TO MAKE 4 PIECES. Crumble & set aside.
Add large chopped onion to skillet, & cook over medium low heat,till onions are carmelized & transparent. Set aside till needed.
Reheat potatoes about 3 minutes in microwave,then add to large bowl.
Add crumbled bacon, carmelized onions, & shredded cheese. Combine together & set aside till needed.
To MAKE PIEROGI DOUGH, ADD FLOUR, SOUR CREAM, BAKING POWDER & EGGS TO A LARGE BOWL.
Using a pastry blender, mix till dough comes together if more liquid is needed add the whipping cream a little at a time, till it reaches the right consistency.
Finish mixing by hand to form a soft & smooth ball. Divide dough into 3 or 4 pieces. Keep in fridge while rolling out 1 piece. To prevent dough from drying out.
Dust counter surface & rolling pen with flour. Take a portion of the dough and roll out as thinly as possible.
Using a 3 inch Round mini Pie cutter or large jar or glass, rub rim in flour, then cut circles in pastry dough.
Add about 1 tablespoon of potato mixture to center of each circle. I shaped mine a little long to make it easier to cover with dough.
Brush outer EDGE of dough with water & fold each round in half.
Pinch together with tines of a fork to seal so no potato mixture leaks out.
Lightly dust a large platter with flour, & place finished pierogi's on platter. REPEAT TILL ALL THE PIEROGI'S ARE MADE. I MADE 38 PIEROGIS from this recipe using the amounts specified.
In a large pot Heat water till boiling, add salt, then drop 6 pierogis in boiling water, and when they float to the top, BE CAREFUL NOT TO OVER CROWD POT OR THEY WILL STICK TOGETHER. REMOVE WITH slotted spoon onto a serving dish or platter. Repeat till finished.
Melt 1/2 to 2/3 stick of butter in large skillet add the SLICED ONIONS & SWEET PEPPERS IF DESIRED.
ADD PIEROGIS & LET BROWN ON EACH SIDE. rEMOVE TO LARGE PLATTER, AND TOP WITH ADDITIONAL CHOPPED GREEN ONIONS if desired. Serve with Sour Cream.
Please NOTE: I am no expert, especially for making Pierogis,as this was my first time, but I used some methods that were best for me, which may or may not be traditional. My family and Neighbors were very PLEASED WITH THE FINISHED PRODUCT & THE RESULTS.
YOUR TECHNIQUE MAY BE DIFFERENT FROM MINE, BUT HOPEFULLY OUR RESULTS WILL BE THE SAME or very similiar. BECAUSE THESE WERE really Really good & very Tasty.
