Fill a saucepan with vegetable oil and heat up slowly to 200°C.
Dry the cut potatoes well over paper towels then add them to the saucepan of oil. Fry about 5 to 7 mins until golden brown. Remove and set aside on paper towels and let them cool before the second fry.
Make sure that the oil has heated up to 175C and do a second fry about 3 mins for extra crispy french fries.
Drain on paper towels and add to a bowl, sprinkle salt and toss to mix.
