Is There Any Way To Salvage A Sweet Potato That Is Starting To Rot?
As a lover of all things sweet potato, I’ve had my fair share of the heartbreak that comes with discovering one starting to rot. Seeing a once vibrant and delicious vegetable slowly wither away is sad. However, over the years, I’ve learned a few tricks to salvage a sweet potato that’s starting to go bad. So, is there any way to salvage a sweet potato starting to rot? The answer is yes, but it depends on the extent of the rot.
First, it’s important to know that sweet potatoes are prone to rotting, especially if stored in a damp or humid environment. To prevent this from happening, make sure to store your sweet potatoes in a cool, dry place with good ventilation. If you notice any signs of rotting, it’s best to act quickly.
If the rot is in the early stages and is only affecting a small part of the sweet potato, you may be able to salvage it. Begin by cutting away the affected area with a sharp knife, removing all the rotten flesh. Then, rinse the sweet potato under cold running water to remove any remaining bacteria. Once you’ve done this, you can cook and eat the sweet potato as you normally would.
If the rot has spread to a larger portion of the sweet potato, your options may be more limited. However, you can still salvage some sweet potatoes by cutting away the rotten parts and using the remaining healthy flesh. Just thoroughly inspect the sweet potato and remove all rotten areas before cooking.
If you’re still unsure whether or not a sweet potato is salvageable, use your senses to help you. A sweet potato starting to rot will often give off a foul odor, so if you catch a whiff of something unpleasant, it’s best to err on the side of caution and discard the sweet potato.
How Long Do Sweet Potatoes Last?
Sweet potatoes are delicious and nutritious root vegetables that can last quite a while if stored properly. When covered in cold water, they can last up to a day. Raw sweet potatoes do not freeze well, but cooked ones can be stored in the freezer for 10 to 12 months with the best quality.
In the fridge, cooked sweet potatoes can last up to four days, while raw ones can last a few weeks when properly stored. Sweat potatoes can last up to two weeks if kept in a cool, dry pantry. While they can lose flavor and texture after 3-4 days, sealing cut sweet potatoes in a plastic bag, or airtight container before refrigeration can extend their freshness for up to 5 days.
What To Do With A Bad Sweet Potato?
- Compost it. If you have a compost bin or pile, toss that bad boy in there. Sweet potatoes make great compost material because they’re high in nutrients and organic matter. Just be sure to chop it into smaller pieces so it breaks down faster.
- Feed it to your pets. If you have a dog or cat, they might enjoy a little bit of cooked sweet potato as a treat. However, if the sweet potato is moldy or visibly spoiled, it’s best to avoid giving it to your pets.
- Use it as a natural dye. Did you know that sweet potatoes can be used to dye fabric? Boil the potato until soft, mash it up, and strain out the liquid. Use the liquid to dye the fabric yellow or orange.
- Turn it into a face mask. Sweet potatoes are packed with vitamins and antioxidants for your skin. Mash up the potato, mix it with a little bit of honey and coconut oil, and apply it to your face for a DIY spa treatment.
- Experiment in the kitchen. Just because a sweet potato is bad doesn’t mean you can’t use it in cooking. Cut off the bad parts and see if the rest of the potato is salvageable. You can try mashing, frying, roasting, or turning it into soup.
- Roast it simply. Assuming you could salvage most of the potato, let’s talk about what you can do with it. One option is to roast it simply. Cut the potato into small chunks, toss it in some olive oil and seasonings of your choice (I recommend garlic powder and paprika), and roast it in the oven at 400 degrees Fahrenheit for about 25-30 minutes or until it’s crispy on the outside and soft on the inside. Voila! You’ve got a delicious side dish.
How To Choose Good Sweet Potatoes?
Here are some tips on how to choose good sweet potatoes:
1. Look for smooth skin
When choosing sweet potatoes, look for ones with smooth skin. Rough or cracked skin can indicate that the sweet potato is older or has been stored improperly, which can affect its taste and texture.
2. Check for firmness
A good sweet potato should be firm to the touch, without any soft or mushy spots. Sweet potato may be overripe or spoiled if it feels soft or mushy.
3. Choose the right size
Sweet potatoes come in a variety of sizes, but it’s best to choose sweet potatoes that are medium to large in size. Smaller sweet potatoes can be tough and fibrous, while larger sweet potatoes can be too starchy.
4. Check the color
Sweet potatoes come in a range of colors, from pale yellow to deep orange. When choosing sweet potatoes, look for ones with a rich, vibrant color. A dull or pale color can be a sign that the sweet potato is old or has been stored improperly.
5. Smell it
A good sweet potato should have a slightly sweet, earthy smell. If a sweet potato smells sour or musty, it may be spoiled.
In conclusion, choosing good sweet potatoes is easy as long as you keep these tips in mind. Look for ones with smooth skin, firmness, the right size, vibrant color, and a sweet smell.
How Can You Properly Store Sweet Potatoes To Prevent Them From Spoiling Too Quickly?
First, it’s essential to understand that sweet potatoes should be stored in a cool, dry place. This means avoiding any areas with excess moisture or heat, such as the refrigerator or a sunny windowsill. Instead, opt for a pantry or cupboard that is well-ventilated and away from any sources of heat.
It’s also important to inspect them for any signs of damage or decay. Any sweet potatoes with soft spots or bruises should be set aside and used as soon as possible to avoid them affecting the rest of your batch.
Regardless of the type of container you choose, it’s important to make sure your sweet potatoes are not overcrowded. This can lead to excess moisture buildup and cause them to spoil more quickly. Instead, aim to store your sweet potatoes in a single layer, with a little bit of space between each potato.
Finally, checking on your sweet potatoes regularly is important to ensure they are still fresh. If you notice any signs of spoilage, such as mold or a foul odor, it’s best to discard them immediately to prevent them from affecting the rest of your batch.

But if the soft spots and bruises are minor, one can simply remove them and continue to enjoy their delicious and nutritious sweet potato.

- Consider taking an over-the-counter medication. If you’re experiencing symptoms like nausea or stomach cramps, an over-the-counter medication like Pepto Bismol or Tums may offer relief.
- Rest and monitor your symptoms. If your symptoms are mild, you may be able to treat them at home. However, it’s important to seek medical attention if they are severe or persist for more than a day or two.
- Learn from your mistakes. Eating a bad sweet potato is not a pleasant experience but can be a valuable learning opportunity. Take some time to reflect on what happened and how you can avoid similar situations in the future.
