Now, here's the thing: if you want your Key Lime Pie to last as long as possible, you need to store it properly. This means covering it with plastic wrap or aluminum foil and keeping it in the fridge at a temperature of 40°F (4°C) or below. You should also make sure it's away from strong-smelling foods, as Key Lime Pie can absorb odors easily.
But, let's get real, who can resist a slice (or two) of Key Lime Pie for that long? I mean, it's a dessert that's meant to be enjoyed, not stored away for days on end. So, go ahead and indulge in a slice (or two), and don't worry too much about how long it will last - after all, it's Key Lime Pie, and it's meant to be savored and enjoyed!
