Cut the potatoes (as explained above). Remember that for crispy fries, it is very important that the slices have a wave shape when cut with a knife or mandolin.
Place the sticks in a bowl of cold water and three tablespoons of white vinegar.
Pat them dry and place them in a pan of boiling water for 1 minute. This step removes excess starch from the potatoes and creates a much smoother texture.
Remove them from the boiling water, rinse them under cold running water and place them in a bowl of ice water. Before moving on to the next step, the potatoes should be dried using paper towels.
Heat the oil in a frying pan over high heat and gradually add the potatoes following the cooking method described above. For a crispier result, we recommend using peanut oil or sunflower oil.
