Prepare the Pyrizhky Dough

1. Mix the 1 tsp. of sugar with the warm water and let it dissolve.

2. Sprinkle the yeast over the water and sugar mixture and let it rest for 10 minutes. This gives the yeast a head start.

3. Scald the milk in a saucepan, or heat it until small bubbles form around the edges of the pan.

4. Add the butter to the hot milk and allow it to melt. Let the mixture cool.

5. Combine the milk and butter mixture, the yeast and water mixture, eggs, salt and 1/4 cup sugar in a large bowl.

6. Mix in the flour 1/2 cup to 1 cup at a time, blending after each addition, until the dough is about the same consistency as bread dough.

7. Turn the dough out onto a clean, floured work space and knead it until smooth and elastic.

8. Put the dough back in the bowl, cover it with a towel and let rise until double in size (usually 1 hour, but this can take longer in cooler weather).

9. Punch the dough down and knead it a few times. Cover it up and let it rise again.

Prepare the Meat Filling

1. Melt 2 of the 4 tbsp. butter in a large frying pan.

2. Mince the medium onion and add it to the pan.

3. Add the other 2 tbsp. of butter and the ground meat to the onions and brown.

4. Cover and let simmer until the meat is thoroughly cooked.

5. Remove the meat from the pan, leaving the fat and juices.

6. Stir in the 1 tbsp. of flour.

7. Add the water or stock and bring to a boil.

8. Return the meat to the pan and let the mixture cool.

9. Chop the hard boiled eggs.

10. Stir in the parsley and eggs. Season with salt and pepper to taste.

Prepare the Mushroom Filling

1. Mince the small onion.

2. Melt the 4 tbsp. butter in a large pan over medium heat. Add the chopped onions and cook until tender.

3. Chop the mushrooms finely while the onions are cooking. When the onions are tender, add the mushrooms and sour cream, reduce heat to low and cook for about 15 minutes.

4. Dice the hard boiled eggs.

5. Add the bread crumbs, dill, eggs, salt and pepper and stir. Let the filling cool.

Make the Pyrizhky

1. Take a piece of the dough (about a third of it) and roll it out on a clean, well-floured work space until it is about 1/2-thick.

2. Cut out the dough with a round or square cutter (about 2 inches wide).

3. Roll one of the squares or circles you've cut out to about 1/4-inch thick.

4. Place a mound of the filling in the center of the dough.

5. Fold the dough in half and pinch along the edges to seal it.

6. Roll the sealed dough ball around in your hands a bit to get it to more uniform shape.

7. Place the ball seam-side down onto the greased baking sheet.

8. Roll out and stuff remaining dough squares or circles and then repeat the process with the other two-thirds of the dough, one third at a time.

9. Brush the prepared buns with melted butter.

10. Cover the pyrizhky with a towel and let rise for 1/2 to 1 hour, or until they look about one and a half to two times as large.

11. Bake at 375 degrees F for approximately 30 minutes or until golden brown.
