My Czech grandmother used to make these also. Except she used egg as a binder and added a little salt and flour in with the potatoes. But for some reason she always grated the potatoes instead of mashing them. I have since learned that they are also called kopytka (Polish) and gnocchi (Italian).
I never made potato dumplings before but these were so easy to make. Next time I would add some seasoning to the mashed potatoes. My boys and I enjoyed these. Made for Spring PAC 2010.
This is the best food in the world and well-written recipe. My family has these every year on Christmas and my grandmother is very protective of the recipe. My family serves this with sauerkraut. Also, if there are any leftovers, we chop it into small slices and fry it in a little oil with some pork. That's the only way grandpa would eat them. It tastes great!
