The storage time for both peeled and unpeeled potatoes in the fridge can vary depending on their condition and the storage method. Here are some general guidelines:
Unpeeled potatoes: Unpeeled potatoes can be stored in the fridge for about 2 to 3 weeks. It's best to keep them in a cool, dark, and well-ventilated place, such as the vegetable drawer in the fridge. Make sure to store them away from onions and other ethylene-producing fruits, as ethylene can cause potatoes to sprout.
Peeled potatoes: Peeled potatoes have a shorter shelf life than unpeeled ones. Once peeled, potatoes should be used within 24 to 48 hours for the best quality and safety. If you need to store peeled potatoes for a slightly longer period, you can submerge them in a bowl of water and keep them in the fridge. Change the water daily to maintain freshness. However, it's still best to use them as soon as possible.
Keep in mind that these time frames are general guidelines, and the actual storage time can vary based on the condition of the potatoes and the temperature and humidity of your fridge. Always inspect the potatoes before use and discard any that show signs of spoilage, such as mold, soft spots, or a foul odor.
If you have a large quantity of potatoes that you won't be able to use within the recommended storage times, you can consider freezing them. To freeze potatoes, blanch them in boiling water for a few minutes, then cool them quickly in ice water. After that, drain and dry the potatoes, place them in airtight containers or freezer bags, and store them in the freezer for up to 10-12 months. However, keep in mind that the texture of frozen potatoes may change, so they are best used in cooked dishes rather than for fresh consumption.
