Okinawan Sweet Potatoes: Believed to have come from the Aztecs of South America with the Spaniards to the Philippines and China in the 1490s, the plant of these sweet potatoes did not reach Japan until the 1600s. The initial planting was in Okinawa—the southern island of Japan—before they were cultivated throughout Japan, hence the name. Eventually these purple tubers ended up in Hawaii and became a part of the native menu—they are also known as Hawaiian sweet potatoes. With a creamy, beige skin on the outside and bluish-purple flesh on the inside, these sweet potatoes are grown in Hawaii for the U.S. market. Okinawan sweet potatoes have a mildly sweet flavor with notes of honey and a dry, very starchy texture. According to The Blue Zones by Dan Buettner, consumption of these potatoes is correlated to living a longer life.
