Add about 1 tablespoon of oil to a large skillet or frying pan and put over medium-high heat. When hot, take a handful of the potato mixture and form into a loose patty. The mixture will be very wet and soft. Drop the patty directly into the hot pan. Fry a couple of minutes until the bottom is golden brown, then flip and fry on the other side. Repeat with remaining potato mixture until all the batter is used up, adding more oil to the pan as needed. Drain the patties on paper towel.
For extra crispy potato pancakes, make the patties very thin.
