(recipe is from my grandmother)
Boil the potatoes in their skins until soft, then skin them. Put potatoes through a ricer. Spread on a towel for a few minutes to remove moisture, then put them in a bowl, add salt, eggs, flour, 2/3 c bread crumbs, and nutmeg, and mix. Form mixture into dry balls (if it seems too moist, add more bread crumbs). Drop the balls into boiling, salted water. When they come to the surface, allow them to boil for 3 more minutes. Remove one and cut it open; if the center is dry, they are sufficiently cooked.
Remove from water and cover with a dressing made as follows: brown butter in skillet, add 1/2 c bread crumbs and onion, and cook for several minutes.
