Yes what you are making are Palacinkes. They way I was taught to pronounce it was "paul-o-sink".
Palacinke is the generic term for pancakes in Czech, as far as what I was taught. Whether they were flour based, potato based, etc.
Unfortunately the grandparents are all gone now, so my knowledge of the language continues to slip. My great grandfather always said I came to America we will speak English. He had quite a thick accent, but learned and spoke English. He said the US gave him the opportunity for a new life by escaping the persecution during WWI, the least he could do was speak the language. Czech was only spoke at home.
