Good morning ladies & gentlemen, it is a popular potato dish both in Hungary and Prague. Do you know it and what do you call it in Russian??? The basic recipe is potatoes (boiled or raw) sliced, layered with some sorf of cream, some use boiled egg, some use cucumber, some use sausage, too and you pour cream on the top and bake it in the oven. Thank for your cooperation and have a productive day. Enco.
