When fruits are cooked, they release delicious juices. The downside of this process is it can leave your pies and cobblers running all over your plate. But as your leftover pies and cobblers cool on the counter or in the refrigerator, these juices start to condense, creating a thicker, tastier treat. To properly preserve fruit pies and cobblers, cover them with plastic wrap or foil and store them on the counter for up to two days. They'll last twice as long if you store them in the fridge. Of course, if your pie is a cream, custard or other variety containing eggs, it must be stored in the fridge and is best enjoyed within two days. If you want to make your sweet treats last longer, store in the freezer for up to four months, but make sure they're wrapped tightly to prevent freezer burn.
