These vibrant, nutrient-rich tubers are not only a delicacy in Hawaiian cuisine but also play a significant role in the state’s agricultural history. In this article, we will delve into the world of purple sweet potatoes in Hawaii, exploring their origins, varieties, and cultural significance.
Introduction to Purple Sweet Potatoes
Purple sweet potatoes are a type of sweet potato that owes its distinctive color to its high concentration of anthocyanins, powerful antioxidants that have been linked to several health benefits. These sweet potatoes are native to the Americas but have been cultivated in various parts of the world, including Hawaii, where they have become an integral part of the local culture. The two main varieties of purple sweet potatoes found in Hawaii are the Uala and the Okinawan sweet potato.
Uala: The Traditional Hawaiian Variety
The Uala is a traditional Hawaiian variety of sweet potato that has been cultivated for centuries. It is believed to have been introduced to the islands by early Polynesian settlers, who brought it from their homelands in the South Pacific. The Uala is characterized by its deep purple color, sweet flavor, and soft, moist texture. It is a staple crop in Hawaiian cuisine and is often served at traditional Hawaiian gatherings and ceremonies.
Culinary Uses of Uala
Uala is a versatile ingredient that can be used in a variety of dishes, from traditional Hawaiian recipes to modern fusion cuisine.

Some popular dishes that feature Uala include poi, a traditional Hawaiian dish made from fermented taro root, and laulau, a classic Hawaiian dish consisting of pork, beef, and fish wrapped in taro leaves.
Okinawan Sweet Potatoes: A More Recent Introduction
The Okinawan sweet potato is a variety of sweet potato that originated in Okinawa, Japan. It was introduced to Hawaii in the early 20th century, when Okinawan immigrants arrived on the islands. The Okinawan sweet potato is similar to the Uala in terms of its deep purple color and sweet flavor, but it has a slightly sweeter and nuttier taste. It is also higher in antioxidants and has a softer, more moist texture than the Uala.
