Authentic Potato and Mushroom Vareniki (Pierogi) Recipe

Ingredients

• 18 ounces potatoes
• salt and freshly ground black pepper
• 3 cups all-purpose flour
• 1 teaspoon salt
• 0.25 cup sour cream
• 0.5 teaspoon baking soda
• 0.5 cup water
• 0.25 cup butter
• 2 onions, finely diced
• 3.5 cups finely chopped button mushrooms

Instructions

1. Boil potatoes in a large pot of salted water until tender, approximately 25 minutes. Drain well and mash thoroughly; season generously with salt and freshly ground pepper.
2. In a large mixing bowl, combine flour and 1 teaspoon of salt. In a separate bowl, mix sour cream with baking soda. Gradually add the water to the flour mixture, then incorporate the sour cream mixture. Knead until a smooth dough forms, wrap in plastic, and chill for 10 to 15 minutes.
3. Melt butter in a skillet over medium heat. Sauté onions until golden brown, about 5 to 10 minutes. Add mushrooms and cook until browned, about 5 minutes. Stir the mixture into the mashed potatoes and combine well.
4. Divide the dough into 4 equal portions and roll each into a 1 1/2-inch thick rope. Cut the ropes into small 1/2-inch pieces. Flatten each piece into a small circle, place 1 teaspoon of potato filling in the center. Fold the dough to form a half-moon shape and firmly seal the edges.
5. Bring a large pot of salted water to a gentle boil. Add the vareniki in batches, cooking until they rise to the surface, about 3 minutes. Continue cooking for an additional 2 to 3 minutes. Remove with a slotted spoon and drain thoroughly in a colander.
