The History of Pizza
Today, pizza ( 披 萨 饼 ) is one of the world’s favorite foods. All over the world, people make different kinds of pizza. 但是披萨饼起 源于哪里And who made the first one ?
People have been making food like pizza for a very long time. Thousands of years ago, some people mixed flour (面粉) with water to ake dough ( 生 面 团 ). They cooked it on hot rocks. People covered the cooked dough with ifferent other foods, like onions, carrots and chicken. They had made the world’s first pizza.
Then in the 1500s some Europeans brought the first tomatoes back from the America. Tomatoes are necessary in making many pizzas today. At first, however, most Europeans thought eating tomatoes would make them sick. So, for about 200 years, few people ate them. Slowly, people learned that tomatoes were safe to eat, as well as delicious. Later, cooks in Naples, Italy, started the tradition of putting tomatoes on dough. It soon became a favorite food there. In 1830, a cook in Naples took another big step in the history of pizza - he opened the world’s first pizza restaurant.
Today, about five billion(十亿) pizzas are made every year around the world. In the United States alone, people eat about 350 slices(片) every second. People may not know it, but every piece is a slice of history.
