Yams vs Sweet Potatoes: The Truth Revealed
Contrary to popular belief, yams and sweet potatoes are not the same thing. Yams are tubers native to Asia and Africa, while sweet potatoes belong to the morning glory family. In the U.S., the term “yam” is often misused and used interchangeably with sweet potatoes. Southern farmers coined the term “yam” to differentiate the orange-fleshed sweet potatoes they were cultivating.
True yams have scaly brown skin and starchy white flesh. They are less sweet than sweet potatoes and are best boiled or slow-braised. It is unlikely that you will accidentally purchase a yam at your local supermarket, as most of the “yams” available are actually sweet potatoes.
| Yams | Sweet Potatoes |
|---|---|
| Native to Asia and Africa | Belong to the morning glory family |
| Scaly brown skin | Smooth skin in various colors |
| Starchy white flesh | Moist or dry flesh in various colors |

Best Practices for Sweet Potato Storage
To ensure the longevity of your sweet potatoes, it is essential to follow proper storage practices. By implementing the right techniques, you can preserve the quality and flavor of your sweet potatoes for an extended period. Here are our recommended best practices for sweet potato storage:

- Let the sweet potatoes cure for approximately two weeks, allowing the sugars to develop and the flavors to intensify.
- Proper Storage Conditions:
After curing, it is crucial to store the sweet potatoes correctly to maintain their quality. Follow these guidelines for storing sweet potatoes:

Proper handling before storage is essential in preserving sweet potatoes. Here are some tips:

Following these best practices will help you maintain the quality of your sweet potatoes and extend their shelf life for up to three months.
