Gather ingredients before starting recipe.
Preheat oven to 325°F
Mix grated potato, onion, flour, one egg and salt in a medium mixing bowl. Stir until the mixture is fully blended.
Heat corn oil to come about 1/4 of the way up in a 10" skillet over medium high heat. Test to see if oil is hot by dropping a very small amount of the mixture in the pan. If it sizzles and rises to the top, the oil is hot enough.
Drop a generous tablespoon of potato mixture in the oil, gently flatten so that the pancake is evenly thick to the edges, and continue to add more pancakes. You should get about 4 pancakes in the pan.
Fry until the pancake gets a golden color on the under side, then flip and fry until the second side is also golden.
Remove to a paper towel lined cookie sheet, immediately salt and continue with the remaining batter until you have made the rest of the pancakes.
Remove paper towel from cookie sheet and replace the pancakes and heat for 10 minutes in a pre heated oven when ready to serve.
