This recipe has been emailed to me from one of the readers. She's mentioned that it has been their family's hit recipe and I think I know why. Pelmeni (a.k.a. Dumplings) on their own are pretty bomb, but to let it swim in delicious, creamy sauce, triples the bombness.
If don't have Pelmeni on-hand, you can use large pasta shells, just fill them with some seasoned ground meat, it would be as close as you can get in flavor.
