Where did potatoes originally come from?
Potatoes originally come from South America specifically from the Andes mountains. They were brought to Europe by early Spanish explorers in the 1500's. They were slowly adopted as a staple because they can grow in many types of soil.
There are over 4000 kinds of potatoes, all cultivars that trace their origin to Peru and Chile.
Mashed potatoes come from the underground roots of plants. Farmers remove the potatoes from underground. Then, the potatoes are sold in stores and at farmer's markets. The potatoes are purchased, washed, peeled, sliced, cooked, and mashed with a potato masher or mixer. Also, instant mashed potatoes come from dried potatoes.
