Yam

What Is Yam?

Yam is the tuberous root of a climbing plant (Dioscorea alata and related species) that forms large underground tubers and is a staple starchy food in Africa, the Caribbean, and Southeast Asia. Its skin is brown and hairy; the flesh may be white, yellow, or purplish.

In English, “yam” is sometimes mistakenly used for sweet potatoes, but the two belong to entirely different plant families. True yam has a drier, starchier texture than sweet potato and must be cooked thoroughly before eating.

How Should You Eat Yam?

Yam can be part of a balanced diet as a source of carbohydrates and fiber. Always cook it thoroughly before eating; raw yam contains compounds that can make digestion difficult.

This is general information; yam is a food and is not a substitute for medical treatment.

How to Choose Yam

A good yam is firm and hard, with moist, shiny flesh when cut and no mold spots. Avoid yams that are soft, sprouting, or moldy.

• It should be firm and hard, without yielding when pressed.
• When cut, the inside should look moist and shiny.
• It should have no mold spots or sprouts.

How to Store Yam

Yam can be stored in a cool, dry, dark place for 2–3 weeks. Like potatoes, it should not be refrigerated; cold damages its texture and spoils its flavor.

Using Yam in the Kitchen

Yam is most often boiled and mashed (as in fufu), fried, or added to stews; it is a starchy staple in African and Caribbean cuisines.

Do People Confuse Yam and Sweet Potato?

Yes, especially on grocery-store labels in the United States, but botanically they are entirely different plants. Sweet potatoes belong to the morning glory family, while true yams belong to the Dioscoreaceae family.
