Vareniki

Sift the flour into a bowl, add the salt, butter, and sour cream, pour in a cup of hot water, and knead the dough.

Turn the dough out onto a floured surface and knead by hand until smooth and elastic.

Cover the dough with plastic wrap and let rest for 10-15 minutes.

Boil the potatoes and mash them until smooth.

Finely chop the mushrooms and sauté them in oil.

Add finely chopped fresh herbs, season with salt and pepper. The filling is ready—time to shape the vareniki.

Cut off 1/3 of the dough. Roll it out into a long strip, about 10 cm wide.

Using two tablespoons, form a ball of filling and place it onto the rolled-out dough.

Moisten the edges of the dough with water. Fold the dough over to enclose the filling.

Cut out the vareniki. Using a glass, stamp out the dumplings.
