For the poppy seed noodles, form the potato dough into thumb-thick rolls, cut into nut-sized pieces, roll by hand on a floured board into oblong noodles (they should be bulbous in the middle, pointed at the ends). Boil in salted water for about 4 minutes (until they float on top), remove from water, drain and toss in ground poppy seeds and melted butter.
Serve the poppy seed noodles sprinkled with powdered sugar.
Preparation Tip:
Applesauce goes great with the poppy seed noodles.
