Place the potato slices in a large bowl and cover with water.
Add the two tablespoons of white vinegar and mix a little.
Leave to rest in the refrigerator for at least 20 minutes . An hour would be ideal.
Then remove the cut shavings from the water and dry them as much as possible with a cloth or paper towel.
Heat the oil well in a saucepan or pan suitable for frying and add the chips.
Add salt to taste and enjoy the crispiest potatoes in the world!
