Storing Uncooked Sweet Potatoes
Now that we’ve explored the wonderful world of sweet potatoes, let’s address the question at hand: do uncooked sweet potatoes need to be refrigerated? The answer depends on several factors, including the storage conditions, the variety of sweet potato, and how soon you plan to use them.
Room Temperature Storage
Uncooked sweet potatoes can be stored at room temperature for a short period. It’s essential to keep them in a cool, dark place with good ventilation.
