My cousin regularly makes a huge platter of potato skins, says they're okay for up to 25 days. How long can potato skins really last when refrigerated?

The humble potato skin is a beloved appetizer that's not only tasty but also quite versatile. They can be served with various toppings and are a staple at many parties and family gatherings. However, when it comes to preserving these delicious bites, it’s important to understand the limits of their shelf life to ensure they remain safe and enjoyable to eat.

Potato skins, like any other prepared food, have a limited shelf life, especially once they have been cooked and exposed to different toppings and oils. The shelf life of potato skins can be affected by several factors including the method of preparation, the freshness of the ingredients, and how they are stored.

The way you prepare your potato skins can impact their longevity. For instance, baking or frying with a light amount of oil can potentially allow them to last longer than if they were smothered in ample amounts of butter or oil, which can turn rancid more quickly.

The shelf life of potato skins is also determined by the freshness of the ingredients used. Potatoes that are fresh and haven't shown any signs of sprouting or greening will contribute to a longer shelf life for the finished product.

Storing potato skins correctly is crucial. They should be kept in an airtight container within the refrigerator, which ideally should be set at or below 40°F (4°C). This will slow down the growth of bacteria that can cause food spoilage.

The USDA recommends storing leftovers, including potato skins, for only three to four days in the refrigerator. This is a standard guideline to minimize the risk of foodborne illnesses. Extending beyond this period may increase the chance of spoilage and bacterial growth, even if the food does not show visible signs of going bad.

Regardless of the recommended guidelines, it's important to also trust your senses. If the potato skins begin to exhibit a strange odor, mold, or an off-taste, they should be discarded immediately.

It's worth noting that claiming potato skins can remain okay for up to 25 days is far beyond the recommended time frame and poses a risk of foodborne illness. Although freezing them could extend their shelf life substantially, once refrigerated, the recommended limit for best quality and safety should not exceed 3-4 days. After this time, even though the potato skins might seem fine, consuming them isn't worth the potential health risks.

In conclusion, while your cousin's culinary endeavors with making large platters of potato skins are commendable, their estimation of the shelf life is greatly exaggerated when looking at food safety guidelines. If you wish to enjoy potato skins beyond a few days, consider freezing them as soon as they've cooled down and then reheating them when you're ready for a treat. Always practice safe food handling and storage to ensure your snacks remain delicious and, more importantly, safe to eat.
