Potatoes are used throughout the world and can be prepared in a variety
of ways.
"The potato is a starchy, tuberous crop. It is the world's fourth-largest
food crop, following rice, wheat and corn.
The annual diet of an average global citizen in the first decade of the
21st century included about 73 pounds of potato.
The potato was first domesticated by the Andean civilizations in the
region of modern-day southern Peru and extreme northwestern Bolivia
between 8000 and 5000 BCE. It has since spread around the world and has
become a staple crop in many countries."
