Place the sifted flour onto the board, add yolks, sour cream, baking powder and vanilla (optional) , alcohol and salt. I used my stand up mixer it is faster and more sanitary.
Mix all the ingredients until a ball forms.
If using a mixer, use a hook and continue kneading for additional 5 minutes on a low speed to medium speed. If using a hand you will have to knead by hand for approximately 5 minutes as well. Try using your roller pin to hit the ball of dough a few times to aerate it. You know when the dough is ready when it no longer sticks to your hands, board or the roller.
Divide the dough into two parts and roll out each part very thinly to approximately 2 mm.
Then form the wings: cut the dough into 10 cm long strips and 3 cm wide strips.
Cut each strip in the middle and put one end of the strip through the cut and pull.
Fry the Faworki in hot oil on one side until golden brown. Best to check the temperature with a cooking thermometer or by placing a piece of dough in the oil, after a few seconds it will come to the top, then you know that the temperature is right.
Then turn Faworki to the other side and fry until golden brown.
After frying, drain on paper towel and leave to cool. Sprinkle with powdered sugar mixed with vanilla sugar (optional). I prefer to place the vanilla in the dough. Enjoy!
