A friend of mine brought those piroshki one day to school and shared them with me. I made my mom call her mom and get a recipe. Ever since then they have become my family's favorite. This dough is perfect for any sweet filled piroshki; I prefer poppy seeds for filling. If you are in for savory piroshki, I have you covered with my sister's recipe - Savory Piroshky. I've been learning my camera and took lots of pictures this time. Although these are not hard to make, hopefully it will make things even easier! My Kitchen Aid Mixer is very helpful with kneading process.
Make small balls out of the dough. Use oil to prevent dough from sticking to your hands. Too much oil on the dough may prevent piroshki from sealing. Flatten out dough and place filling inside. Fold over the sides and pinch the edges together to seal the dough. SIDE NOTE... Yeah, I am way overdue for a manicure. lol :)
I have only made poppy seed filling in a Vitamix blender and it worked great for me. Soak poppy seeds in hot water for 15 minutes. Drain out all water from poppy seeds, combine them together with condensed milk and sugar. Blend for about 30 seconds or until texture is smooth.
