Yam Root
Dioscorea alataA staple starchy root of African, Caribbean, and Southeast Asian cuisines. Often confused with sweet potato but belongs to an entirely different plant family botanically.
What Is Yam?
Yam is the tuberous stem of a vine plant (Dioscorea alata and related species) that forms large tubers underground, one of the staple starchy foods of Africa, the Caribbean, and Southeast Asia. Its skin is brown-hairy, and its flesh can be white, yellow, or purplish.
In English, the name "yam" is sometimes mistakenly used for sweet potato too; yet the two are from completely different plant families. Genuine yam has a drier-starchier texture than sweet potato and must always be consumed cooked.
