"My mother called this "Dough Fish". The apples were sliced onto circle of dough made with mashed potatoes. A little sugar, cinnamon and butter was put on the apples and the dough circle was rolled up and put into a 9 X 13 pan along the short side. Many more of these rolls were added to the pan, even squished in and it was baked. We ate these dough fish with milk poured on them. That was our supper."
Mavis,
I looked up 'fish dough' and all I came up with was dough to catch fish. Was your fish dough maybe a Pierogi dough?
Also, do you know what temperature for the oven? This all sounds so wonderful, I would like to try it.
