With the paddle attachment, add half of the liquid into the dry ingredients and combine. Slowly add in little by little of the liquid. If there is still dry ingredients at the bottom of the bowl, add a little bit more liquid and mix together. You might not need all of the liquid. The dough will be slightly sticky but not wet.
Once the dough is ready, you are ready to start making perogies. Remove the perogie filling from the fridge.
Use a tablespoon of dough and roll it into a ball. Place a sheet of plastic wrap down and place the ball on one side. Fold over the plastic wrap to create a book.
Using a rolling pin, roll the dough out between the plastic wrap until it is very thin.
Using a tablespoon, scoop the potato filling and place it in the middle of the perogie wrapper.
Fold one side of the perogie over to the other and seal it around all the sides.
Using a glass or a cookie cutter, cut the periogie through the plastic wrap. Remove one side of the plastic wrap and peel it off of the other side of the plastic wrap. Place the periogie on a parchment paper lined baking sheet.
Continue this process until you have run out of dough.
Once you have filled the tray, put it into the freezer and work on the rest.
Once they are frozen, about an hour, remove them from the freezer and put them in a freezer bag. Store in the freezer until you are ready to use.
Cooking
Boil a large pot of water.
Add in the perogies to the pot of water. Cook for 5 minutes or until they float. Remove from the water.
If you would like to pan fry, heat up a frying pan with some oil and add in the perogies that have been boiled.
Top with onions, bacon, cheddar cheese and sour cream. ENJOY!
