Types of Sweet Potatoes: Japanese, Hannah, Jersey and More

The appearance and flavor of sweet potatoes varies from those of ordinary potatoes. Several nations love sweet potato varieties like Beauregard and Jewel. Sweet potatoes, on the other hand, come in a variety of shapes and sizes. White or orange flesh is found in sweet potato varieties, and purple flesh is found in certain types.

Sweet potatoes are extremely adaptable when it comes to cooking. Sweet potatoes may be cooked, used in casseroles, or baked. Purple sweet potatoes are utilized to dye desserts in certain nations. Whether you prefer white or purple sweet potatoes, a foray into various types is sure to be fun. The most common varieties of sweet potatoes are described in this article. You’ll learn about their skin, meat, and flavor profile.

What are Sweet Potatoes?

The botanical name for all sweet potato varieties is “Ipomoea batatas.” The family Convolvulaceae (morning glory) and the order Solanales both have tuberous starchy roots. In Central and South America, sweet potatoes are native to tropical countries. Sweet potatoes are simply referred to as batatas in most Spanish-speaking nations. Several nations with a hot and humid environment have domesticated sweet potatoes.

Sweet potatoes, sometimes known as yams, are a common vegetable in North America. Sweet potatoes are now grown by a number of nations across the globe, including Australia, Asia, Pacific islands, and Europe. The most popular flesh types in these nations are the orange and white.

Sweet potatoes have huge tubers with an oblong or oval form that tapers to a tip, which are the edible part. Pink, red, orange, creamy white, copper, and light tan are some of the various colors of sweet potato skins. The flesh color isn’t determined by their skin tone. The Japanese Okinawa purple sweet potato cultivar, for example, has beige skin and dark purple flesh. Hannah has a light tan skin and yellow flesh, making her a popular batata (sweet potato).

Yams or sweet potatoes – what’s the difference?

It’s surprising to learn that sweet potatoes are actually tubers that are referred to as yams. The genus Dioscorea belongs to the Dioscoreaceae family of tuberous roots. True yams are a type of tuberous root. As a result, sweet potatoes and yams are completely unrelated. When it comes to form, skin color, or flesh color, yams and sweet potatoes may appear similar. It might be tough to tell the difference between yams and sweet potatoes in photographs.

True yams, on the other hand, contain more starch and less water than sweet potato varieties. Sweet potatoes are also indigenous to the Americas, whereas yams are from Asia and Africa. Tubers labeled as ‘yams’ in your neighborhood shop are most likely one of many types of sweet potato. True yams are actually quite uncommon to come across in the United States. Throughout the late 1800s, it appears that calling sweet potatoes yams became popular in the United States.

Is a sweet potato a true potato?

If sweet potatoes are a kind of actual potato, there is still some debate. The nightshade family Solanaceae includes traditional potatoes, such as those used to make fries, potato mash, and roasting potatoes. To differentiate them from batatas, or sweet potatoes, potatoes are sometimes referred to as “white potatoes” or “Irish potatoes.” Sweet potatoes are, therefore, a distinct kind of vegetable from potatoes.
