It might be Tocsni you are speaking about (I posted your question on our Facebook page and someone answered there). You can find a recipe in Hungarian at: http://www.mindmegette.hu/tocsni.recept
To make it short in English you need 1kg potatoes, 2 eggs, some spoons of flour and oil. Mash the potatoes totally, mix them with the eggs and the flour. Here you can also add salt, pepper and garlic. Pour the oil into a pan, heat it up, and then take parts of the dough and place it in the hot oil. You can shape them with a spoon. They should be fried there for 4-5 minutes on each side.
Not sure if this is it, but maybe?!
