The only way you should store sweet potatoes is by keeping them in a cool, dry, and well-ventilated space, away from direct sunlight. A pantry or cupboard works well as it keeps the sweet potatoes at an ideal temperature range of 55 to 60 degrees Fahrenheit (13 to 16 degrees Celsius).
Storing them in a cool area helps prevent them from sprouting or spoiling too quickly. It's important to avoid refrigeration, as cold temperatures can affect the sweet potato's texture and taste, making it unpleasant when cooked.
For the best results, sweet potatoes should be stored in a breathable container, such as a paper bag, a basket, or a cardboard box. This allows air to circulate around the sweet potatoes, reducing the chances of mold or rot forming.
Sweet potatoes should never be stored in plastic bags, as this traps moisture and increases the risk of spoilage. Additionally, you should inspect the sweet potatoes regularly, removing any that show signs of damage or decay. This will help preserve the others and prevent contamination.
It's important to note that sweet potatoes should not be stored near onions, as the gases released by onions can cause sweet potatoes to spoil faster. When sweet potatoes are stored properly, they can last up to two to three weeks.
If you want to extend their shelf life further, consider storing them in a root cellar or a cool basement, where temperatures are consistently low and stable. Sweet potatoes can also be frozen for long-term storage, but it's essential to cook or blanch them first to preserve their quality.
After cooking, allow the sweet potatoes to cool and then place them in an airtight container or freezer bag before freezing. This method helps retain their flavor and nutritional value.
In conclusion, to ensure that your sweet potatoes stay fresh for as long as possible, store them in a cool, dry, and well-ventilated area, away from sunlight and moisture, and be mindful of the conditions surrounding them to avoid spoilage.
