Scrub and wash the potatoes.
Slice the potatoes with a mandolin slicer or knife.
Place the potatoes in a bowl filled with water and soak them for an hour or so.
Transfer the potatoes to a pot, fill with fresh water and boil them until tender - less than 10 minutes.
While the potatoes cook, fill a deep pot with your cooking oil. You need enough oil to cover the fries as you cook them in batches. Bring your oil up to 400 degrees.
Drain the water off of the potatoes.
Turn off your stove prior to adding your first batch of potatoes to the oil. We do this to prevent fire in case of a boil over. Begin adding potatoes in batches. Turn your stove back on once you are certain a boil over won't happen.
Cook your potatoes in the hot oil, in small batches, until "they are the right color." A nice golden brown french fry is ready to come out!
Drain your french fries on cookie sheets lined with paper towels. Salt immediately.
Snack on these fries while you finish cooking the rest!
