With its wide variety of styles and tastes, pasta is considered one of America's favorite foods. In the year 2000 alone, Americans consumed 1.3 million pounds of pasta. That’s enough to wrap the world in pasta 9 times! A trip to the grocery store will reveal the amazing variety that pasta offers. Pasta comes in many different shapes and sizes. Some are string shaped like spaghetti and vermicelli. Others are ribbon shaped like fettuccine and linguine. There are short tubes like elbow macaroni and penne, but there are also unique shapes like farfalle and rotelle. Other types include large sheets like lasagna and stuffed pasta like ravioli, manicotti, and tortellini.
The shape and characteristics of each variety's surface makes it better suited for certain kinds of sauce. Fettuccine goes best with alfredo sauce, and spaghetti goes best with tomato sauce. Lasagna wouldn’t be lasagna without those characteristically large sheets, and macaroni is a must in macaroni and cheese.
