Potato, Mushroom and Cheese Pierogi in Egg Dough
Soft dumplings filled with mashed potato, mushrooms, onion and cheese, boiled until tender.
These Polish-style pierogi have a soft, simple dough around a filling of potato, browned onion, mushrooms and cheese. The source describes baking pastry pockets, but pierogi are typically boiled dumplings; this adapted method forms half-moons, seals them firmly and simmers them in batches. Pan-fry the boiled dumplings if you prefer browned edges. The cheese filling is a hearty variation rather than a claim about a specific Christmas Eve tradition. Boil potatoes in salted water until tender, about 15 minutes. Drain well and mash until smooth. Heat oil in a skillet. Cook onion and mushrooms 8 to 10 minutes until soft and most moisture has evaporated. Cool slightly, then mix with potato, cheese and pepper. Combine flour and salt. Add egg, warm water and melted butter; mix and knead 5 minutes to a smooth dough. Cover and rest 20 minutes.
