Pour the lukewarm milk into a large bowl. Stir in the sugar, 1 tablespoon of flour and the yeast. Let it stand for 10 minutes.

Add in the baking powder, salt, vegetable oil, egg whites and 3 cups of flour. Stir with a wooden spoon until the dough is well mixed, then turn it out onto a lightly floured surface.

Knead the dough for 10 minutes, then put in a large bowl, cover it with a dish towel and allow it to rise for about 1 hour.

Preheat your oven to 375

Punch down the dough and knead for another 5 minutes until all the air is out.

Roll it into a log and cut it into 3 equal pieces

Take one piece and roll it out to about the size of a medium round pizza.

Cut the rolled out dough into 8 equal triangular slices, a pastry roller or pizza cutter works great for this.

Place a tablespoon of the feta cheese at the widest part of the triangle.

Beginning at the widest point of each slice, roll it toward the narrow tip.

Place on a lightly greased cookie sheet and continue until all the dough is used.

In a small mixing bowl, whisk the egg yolks and brush each croissant with the egg yolk.

Sprinkle with sesame seeds and place a few nobs of butter around the baking sheet

Bake for 15-20 minutes or until golden brown.

They are delicious, warm out of the oven

Enjoy with a shopska salad or tarator.
