Did anyone say
potato pancakes? Can be a side dish or a main dish.
Grate the potato into a beaten egg with about 2 TBs flour. Proportions aren't terribly important. Ladle them onto a hot frying pan, forming them about 4 inches in diameter.
Good with onion in them, and green onions served on top. Better served savory than sweet, though could go either way.
I may be weird, but I also like potato pancakes served cold, so leftovers are good.
