1Wash potatos (Russet is best) slice with mandolin or just use a great potato pealer. place sliced potates in cold salted water (takes out starch)
2lay on cloth and pat dry.
3Heat your oil ( I just use veg oil but peanut is best) to 350. place the potatos in but don't crown them.
They will be golden in a few minutes so don't walk away.
Take them out and place on a paper towel and sprinkle with salt.
