Potato pancakes are shallow-fried in a pan and cannot be made in a slow cooker. Traditional recipe ingredients may vary, but potato pancakes are always cooked at medium-high heat in oil in a frying pan or skillet, according to Chow.com.
Potato pancakes are prepared with shredded potatoes, finely chopped green or white onion, salt and pepper, and egg. Some potato pancake recipes call for nutmeg. For best results, drop balls of batter into 1/4 inch of heated oil, flatten slightly with the back of a spoon, and fry until golden brown on both sides. Serve hot with a dollop of sour cream or applesauce.
Potato pancakes called latkes are commonly served during Hanukkah. In Germany, potato pancakes are referred to as Kartoffelpuffer
