Cut the potatoes into strips about ¼-inch thick and 3-inches long, then Soak in cold water to remove excess starch. When ready to move on, drain and pat the fries completely dry with a towel.
Pour enough oil into a large, deep pot to come up about 4-inches. The pot should be no more than half full (or it will overflow when you add the potatoes). Heat over medium heat until the oil reaches 300°F (150°C).
First fry. The drain the potatoes. Then second fry.
Transfer to the wire rack (preferably with fresh paper towels!) to drain, then season immediately with Kosher salt and additional flavoring, such as garlic or herbs.
