Uses

Prized in Hawaiian and Okinawan cuisines, Okinawan Purple is steamed, roasted, mashed into vibrant side dishes, or used in purple sweet potato pies and haupia desserts.

Historical Origin

Originating in the Americas, this purple sweet potato reached Japan through trade routes in the early seventeenth century and became a vital staple crop in the Ryukyu Islands (Okinawa). It was brought to Hawaii by Japanese immigrant laborers in the late nineteenth century.
