Ukrainian Vareniki with potatoes recipe

                                                                                         Ingredients:
325 g wheaten flour 
150 g water
1/2 egg
sour cream to taste 
salt to taste 

for making forcemeat:
560 g potato
100 g onion
40 g oil
ground black pepper to taste
salt to taste

Directions:
Unleavened dough. Heat up a half-portion of water to 95 – 98 °C. Add the water in sifted flour and mix very well. Beat up eggs with salt and remaining water at room temperature. Mix well until the mixture has a homogeneous and thick texture and put in a warm place for 30 minutes.
Stuffing. Peel and boil potatoes, dry it a little and rub hot through a sieve, season with onion, fried in oil, pepper and salt (remain some portion of braised onion for seasoning cooked vareniki).

Roll out the dough into a 1,5 mm thick layer. Place prepared stuffing, shaped into balls, through a whole width of rolled out dough layer, stepping back 3 – 4 cm from its ends. Cover the stuffing with dough layer, pressing it around each ball, and cut vareniki out with a special form. Use again the remaining dough for rolling out.

Immerse each varenik separately into boiling salted water, separating it carefully from bottom of a saucepan with skimmer, and cook for 6 – 8 minutes at moderate boiling.

Take vareniks with skimmer out of a saucepan, let the water pour down, season vareniks with onion, braised in oil, and pour sour cream over it.
