What is a Purple Sweet Potato?

Potatoes are native to South and Central America, and come in a variety of hues. Red, white, brown, and purple potatoes have grown and been used in South American cuisine for centuries. They were discovered by Christopher Columbus in the 1500s, and after being taken back to Spain, began being grown world-wide.

Purple sweet potatoes are now grown around the world, with particular popularity in Japan. Because of the popularity of Japanese purple sweet potatoes, growers in the US have begun producing these as well.

Purple sweet potatoes can have a reddish purple or even white skin, with a deep purple hued flesh.

There are also sweet potatoes with reddish-purple skins, with white flesh.

They taste similar to an orange sweet potato, and even have a similar nutrient profile, but the difference in color means they are lower in beta-carotenes, but higher in anthocyanins.
