What Are Purple Sweet Potatoes?
Purple sweet potatoes, sometimes called Okinawan sweet potatoes or Japanese purple yams, are root vegetables with vibrant purple flesh and a slightly sweet, nutty flavor.

Originating in Central and South America, purple sweet potatoes became a staple in Asian cuisine, especially in Japan and Hawaii. Today, they’re gaining popularity worldwide for both their flavor and visual appeal.
