How long does it take an apple pie to rot at a window?

It's impossible to give you a specific timeframe for how long an apple pie will take to rot at a window. Here's why:

* Temperature: The temperature outside your window will drastically affect the rate of spoilage. A hot, sunny window will speed up the process significantly compared to a cool, shady one.

* Humidity: Moisture is a big factor. A humid environment encourages mold growth, which is a sign of spoilage.

* Pie Composition: The type of apple pie itself matters. A pie with a lot of sugary filling will spoil faster than one with a lower sugar content. The crust also plays a role - a flaky crust will dry out faster than a thicker, denser one.

* Protection: Is the pie covered or exposed? A covered pie will stay fresher longer.

General Rule of Thumb:

* Refrigeration is best: To keep an apple pie fresh for the longest time, store it in the refrigerator.

* Room temperature: An apple pie left at room temperature (especially at a window) is likely to spoil within a few days.

* Signs of Spoilage: Watch for mold, a sour smell, and changes in texture.

If you're unsure if your pie is still good, it's best to err on the side of caution and throw it away.
