Where does the sweet potato come from – and what makes the batata so special?
The potato originally comes from South America. It was the Spaniards who brought the tuber to Europe in the 15th century. Today, therefore, it is not only grown in the tropics and subtropics, but also in Italy, Portugal and Spain. The botanical name for the sweet potato is Ipomoea batatas and it's therefore also known as batata. It is the starchy tuber of the sweet potato plant. The skin of the sweet potato can have a light brown, reddish or even purple color. The inside of the tuber, on the other hand, tends to be white, yellowish or deep orange in color. The large root tubers can weigh up to three kilograms, the average weight, however, is only 300 g.
