Is it unsafe to cook a frozen peach pie that has been left out on the counter all day?

It's not recommended to cook a frozen peach pie that has been left out on the counter all day. Here's why:

* Bacteria growth: Leaving frozen food at room temperature for extended periods allows bacteria to multiply rapidly, potentially leading to food poisoning. This is especially true for pies with a filling like peaches, which are susceptible to spoiling.

* Quality degradation: Even if the pie doesn't become unsafe to eat, the quality will likely be compromised. The peaches may become mushy and lose their flavor, and the crust might become soggy.

Instead of cooking it:

* If the pie was out for less than 2 hours: You can safely refreeze it and cook it later.

* If the pie was out for longer than 2 hours: It's best to throw it away and start with a fresh one.

General rule of thumb: Never leave frozen food out at room temperature for more than 2 hours (or 1 hour if the temperature is above 90°F).
