Today I'm back with a recipe from an old Soviet book. He attracted my attention with an unusual way of making potato dough. It looks like a potato sponge cake, which is probably why the dough turns out to be unusually tender. The filling in the pie is chicken-mushroom with the use of dried mushrooms. Breadcrumbs on the surface of the pie create an unusually crisp crust. In general, it's delicious! Very TASTY!
