    The most popular food in America was invented because a cook got angry. George Crum was a cook at a restaurant in Saratoga Springs, New York. One day in 1853, a customer(顾客) who had ordered fried(油炸的) potatoes sent them back to the kitchen. He wanted the cook to slice(切) them thinner and fry them longer. George Crum had a bad temper(脾气), and he thought the potatoes were fine the way he made them. To teach the customer a lesson, he sliced potatoes very thin and fried them until they were crispy(脆的). But instead of being angry, the customer loved the new fried potatoes. He asked for more. Other people who tried them like them too, and customers kept asking for them. Far many years, people called them Saratoga chips after the town where they were first made.

    Even now, after more than 150 years, potato chips are very popular. At least one of every ten potatoes grown in the United States is made into potato chips. So if you like potato chips, be glad George Crum had a bad temper!
