Instructions
Pierogi Dough
In bowl of stand mixer fitted with dough hook, combine flour and salt on low speed. Gradually add boiling water, beating until dough comes together. Increase speed to medium-high and beat dough until smooth and elastic, about 5 minutes. Place dough on floured work surface and cover with tea towel; let rest for 15 minutes.
Mushroom Filling
Heat oil and butter in large skillet over medium heat. Fry onion until softened, about 5 minutes. Increase heat slightly; add mushrooms and cook, stirring, until golden brown and moisture has evaporated, adding more oil if needed. Add garlic and parsley; season with salt and pepper. Cook, stirring, for a few minutes. Scrape into shallow bowl. Let cool.
Perogies
On lightly floured surface, roll out dough until 2 mm thick. Using 9-cm round cutter, cut out 30 circles; place on sheet of parchment paper and cover with tea towel to prevent drying out.
To fill, working with dough round, place 2 tsp of the mushroom filling in centre. Dip finger in small bowl of water and wet dough edges; fold over filling, gently stretching and pressing to remove air. Pinch edges to seal. Place pierogi on another parchment sheet and cover. Repeat with remaining dough and filling.
Bring large pot of water to a boil and cook pierogies in batches for 6 to 7 minutes. Remove pierogies and place on large plate.
Melt butter in saucepan over medium heat; add pierogies without crowding the pan and fry on one side until bottoms are golden brown, 3 to 4 minutes. Deglaze with vinegar. Serve garnished with caramelized onions and sour cream.
