There are many varieties of sweet potatoes; some of the more common ones are: Beauregard, Covington, Jersey, Jewell, Kotobuki (Japanese), and Okinawan (purple), Goldrush, Georgia Red, Centennial, O'Henry, and Evangeline.
Do not store raw sweet potatoes in the refrigerator.
Keep unwashed sweet potatoes in a cool, dry location away from light to prolong shelf life; these are a good item to store in your pantry. They will keep for about 2 weeks.
Cooked whole or pureed sweet potatoes keep 1 week in the refrigerator.
If you store sweet potatoes a cooler location, about 55°F (12.8°C), they will maintain their freshness for a month.
Cooked, mashed sweet potatoes freeze well.
Many people think a sweet potato and yam are the same vegetable; technically they are different. Sweet potatoes are members of the morning glory family, and originate from South America; they are a moister and sweeter vegetable than the yam. Yams are a member of the yam family (closely related to lilies) and originate from West Africa and Asia. Yams are drier and starchier than sweet potatoes.
