1. Prepare the Dough (about 1 hour)

• In a large mixing bowl, combine your Perfect Yeast Dough. Allow it to rise in a warm place until doubled in size, which typically takes about 1 hour.

2. Divide the Dough (10 minutes)

• Once the dough has risen, divide it into 24 equal pieces. The easiest way is by cutting the dough in half and continuing to divide until you have uniform pieces.

3. Shape the Piroshki (30 minutes)

• Roll out each piece into an oval shape, roughly 3 inches by 4 inches.
• Spoon about 1 tablespoon of jam onto one side of the oval. Fold the dough over to create a pocket, ensuring the filling is sealed inside.
• For extra flair, make minor cuts across the top of the piroshki to create a sliced effect.

4. Let Them Rise Again (30 minutes)

• Lay out the piroshki on a baking sheet lined with parchment paper. Cover them with a kitchen towel and allow them to rise in a warm place for at least 30 minutes.

5. Prepare to Bake (10 minutes)

• Preheat your oven to 350°F (175°C).
• Brush the tops of the piroshki with the whisked egg for a beautiful golden finish.

6. Baking Time (45 minutes)

• Bake for about 30-45 minutes, or until piroshki are beautifully golden brown. Keep a close eye on them!

7. Store Properly

• Once done, transfer to a cooling rack and, once completely cool, keep them in an airtight container. They can stay fresh for several days—though I doubt they’ll last that long!
