Thousands of Potatoes From the Andes
The potato is a food that most of us know in only a few shapes, such as fries or chips. In the Andes Mountains of South America, the place where potatoes first came from, there are thousands of kinds. They come in colors that include purple, red, yellow, and even speckled pink. Some are as small as a marble, and some are as big as a fist.
Farmers in Peru and nearby lands grow many different kinds in the same area. Some do better in the warm valleys, while others can stand the cold on high slopes. Growing many kinds is a way of staying safe. If one sort gets sick or a frost comes, the others may still survive.
The Andes people also have a clever way to store potatoes. In the high mountains, nights are freezing and days are sunny and dry. Farmers spread small potatoes on the ground to freeze at night. During the day, people press the water out by stepping on them. After several days, the potatoes become light, hard, and dry. This food is called chuño, and it can be kept for a very long time.
Potatoes spread from the Andes to the rest of the world and now feed millions of people. Their home mountains still hold the greatest variety.
