Place the potatoes in a cheesecloth and wring, extracting as much moisture as possible.

In a medium bowl stir the potatoes, onion, eggs, flour and salt together.

In a large heavy-bottomed skillet over medium-high heat, heat the oil until hot.

Place large spoonfuls of the potato mixture into the hot oil, pressing down on them to form 1/4 to 1/2 inch thick patties.

Brown on one side, turn and brown on the other.

Let drain on paper towels. Serve hot!
