Would potatoes be good left out cooked?

No, cooked potatoes should not be left out at room temperature for an extended period. Here's why:

* Bacteria Growth: Cooked potatoes provide a perfect environment for bacteria to grow rapidly, especially at temperatures between 40°F and 140°F (4°C and 60°C).

* Foodborne Illness Risk: Consuming bacteria-contaminated potatoes can lead to foodborne illnesses like botulism, which can be very serious.

* Spoilage: Cooked potatoes will start to dry out and become less appealing in texture and taste.

Safety Guidelines:

* Refrigerate promptly: Cooked potatoes should be refrigerated within two hours of cooking.

* Store properly: Store in airtight containers or wrap tightly in plastic wrap to prevent drying out.

* Use within 3-4 days: Refrigerated cooked potatoes are best consumed within 3-4 days.

Exceptions:

* Cold potato salads: These are designed to be served cold and are typically made with ingredients that help inhibit bacteria growth.

* Potatoes cooked at very high temperatures: Some methods, like deep-frying, create a barrier that slows down bacterial growth. However, it's still best to refrigerate promptly for optimal safety.

In conclusion, it's not safe to leave cooked potatoes out at room temperature for long periods. To prevent foodborne illness and maintain quality, always refrigerate them promptly and consume them within a few days.
