Peel and grate the potatoes or shred with a food processor.
Place the shredded potatoes in the middle of a large piece of cheese cloth or cotton dish towel. Pull the cheese cloth up around the potatoes, then squeeze while holding it over a bowl. Remove as much liquid as possible.
In a mixing bowl stir together the potatoes, onion, flour, eggs, salt, and pepper.
Cover the bottom of an electric skillet with vegetable oil. Set the temperature to 375°. Allow the oil to get hot.
Using a large serving spoon, scoop up some potato mixture and gently place it in the skillet. Then use the back of the spoon to flatten it into a pancake. Repeat.
Cook each side until golden brown, about 3 minutes.
Place the cooked pancakes on a plate lined with a paper towel.
Serve with applesauce and/or sour cream.
