Potato latkes are enjoyed by many European cultures. They are an absolutely fabulous way to serve potatoes and take very little time at all to prepare.
Grate the potatoes and onion in a food processor fitted with the grater blade. Turn out on to a clean dish towel and wrap, twisting the edges to squeeze out all of the liquid.
Transfer to a large bowl and beat in the eggs and matzo meal. Season with salt and pepper.
Heat 1 inch of oil in a large, heavy-bottom skillet. Drop tablespoons of the potato mixture into the hot oil and cook for 2 minutes, until well browned on the bottom. Turn and cook 1-2 minutes on the other side or until well browned.
Transfer to paper towels to drain. Continue with the rest of the batter. Serve warm with apple sauce or sour cream (or both). Latkes can be reheated in a moderate oven.
