Tip for Getting Crispy Fries

Peel the potatoes and cut them into sticks about 1 cm thick (you can leave them with the skin on but you must wash them very well).
Place the cut potatoes in a large container and pour water to cover them.
Add the two tablespoons of vinegar and mix a little.
Let sit in the refrigerator for at least 20 minutes. An hour would be ideal.
Remove the potatoes from the water and dry them as much as possible (you can use a cloth or napkins).
