Step 1

In the bowl of your mixer, whisk together 1 cup warm water, 1/3 cup buttermilk, 1/2 Tbsp sour cream, 1 large egg, and 1 tsp salt, just until blended. Note: dough can be made by hand but the mixer is much easier.

Step 2

Using the dough hook attachment, add 2 cups flour and mix on speed 2 until incorporated.

Step 3

Add remaining flour 1/2 cup at a time allowing each addition to incorporate before adding more. Add the last bit of flour 1 Tbsp at a time just until dough no longer sticks to the sides of the bowl. Let the dough knead on speed 2 for 15 minutes. Dough will be soft elastic and feel slightly sticky to the touch, but won’t stick to your fingers.

Step 4

Sprinkle a clean work surface with flour. Working with half of the dough at a time, roll it into a thin disk about 1/8" thick. Flipping the dough over once or twice while rolling will make it easier to work with. Cut the dough into circles using a cookie cutter or drinking glass with a 3" rim.

Step 5

Place a round of dough in the palm of your hand with the stickier side up. Add 1/2 tsp sugar to the center and about 5 blueberries. Bring the edges together and pinch tightly to create a strong seal, making sure the sugar does not spill onto the edges. Transfer finished pierogi to a floured cutting board.

Step 6

Blend the remaining scraps of dough into remaining dough half, and repeat steps 4 and 5 until all pierogi are finished.

Step 7

In a large pot, bring 4 quarts water to a rolling boil and add 3/4 Tbsp salt. Carefully place half of finished pierogi in boiling water a few at a time (drop them close to the surface of the water to avoid hot splashes). Once pierogi float to the top, cook 1 1/2 to 2 minutes longer then remove with a slotted spoon and place into a colander to drain.

Step 8

When plating pierogi, drizzle sugar in between layers of cooked pierogi to keep them from sticking to each other. The sugar will melt over the hot pierogies and turn into a light syrup. Serve with sour cream or eat them as is. These are best eaten fresh and warm :).
