The Sweet Potato vs. The Yam
It seems that most people get confused as to what is a sweet potato and what is a yam! In fact, in the United States, most people use both terminologies to refer to a sweet potato, when neither of these two vegetables is related!
The sweet potato is found in tropical America and is a part of the Morning Glory family.
The yam is a tuber (a bulb) of a tropical vine found in Central & South America, as well as the West Indies, Africa and Asia. Varieties There are mainly two varieties of sweet potato. The pale sweet potato has a very thin yellow skin with a bright yellow flesh. This variety is neither sweet nor moist, but more the texture of a white baking potato. The darker skinned sweet potato has a thicker orange skin with a sweet moist flesh.
The true yam is not marketed or grown widely in the United States. Where it is marketed, is usually in Latin American markets. A yam can be as small as a potato and can grow as large as 7 feet and weigh over 120 pounds! The flesh can range in color from off-white to yellow to pink to purple!
