A cranky guest complained about a chef's fried potatoes, calling them too thick and soggy. The chef sliced the next batch paper thin and over-salted them as a trick, but the guest loved them. This new snack of ultra-thin, crispy fried potatoes became known as "Saratoga Chips" and grew into a popular regional and eventually mass-produced snack food sold around the world under various brand names and flavors.
