Where do they come from?
Origins and varieties

Origins: This tuber, native to Central America, is not related to potatoes, despite popular belief. The bell-shaped flowers indicate that it is more closely related to other plants with this characteristic, plants in the Convolvulaceae family, such as morning glories. Today, China, Nigeria, the United Republic of Tanzania, Uganda, Indonesia, Vietnam, and the United States are the biggest sweet potato producers.

A staple in both Asia and Latin America, sweet potatoes are also widely enjoyed in the southern United States. French production remains confidential and is almost exclusively concentrated in the country’s overseas administrative departments in the West Indies.

Varieties: There are over 400 sweet potato varieties, with skins ranging in color from white and yellow to red and purplish, while the inside can be white, yellow, or orange. Sweet potatoes can be divided into two categories, moist and dry.

  • Moist sweet potatoes are mainly eaten in North America and Europe. They are sweeter, orange in color on the inside, and become softer when cooked.
  • Dry sweet potatoes are more popular in South America, Asia, and Africa. They are whitish or yellowish on the inside, less sweet, and starchier in texture after cooking.
