Deep-fried potatoes gives us french fries. And for many, french fries are the best things potatoes have to offer. When it comes to making fries from scratch, be sure to let the cut potatoes soak in water for at least 30 minutes to get rid of excess starch. Also, double frying is key. Fry first at a lower temp (300F) to soften the potato, let them dry on a paper towel, and then fry them again at a higher temp (375) until they're golden and crispy on the outside.
