> Freezing the potatoes causes their moisture to convert to ice, forming sharp, jagged crystals. These crystals damage the cell structure of the potato, making it easier for them to be released once they are heated and convert to steam.
Yeah, you can buy those all-natural 100% potato french fries from the supermarket and fry them into something truly fantastic. When restaurant fries taste "frozen" it's because they're not being refried well.
