While nothing quite compares to a fresh apple, freezing apples for use in cooking or baked goods is an easy way to manage an unexpected overstock and will keep those cobblers, pies and dumplings coming all year long.
There are a couple of things to consider before rushing to the freezer. Sweeter apples such as Fujis or Galas are more likely to hold their flavor than tart varieties, but any apple will do fine in the freezer for six to nine months.
Perhaps more important to keep in mind, though, is that freezing an apple does alter the texture, leaving the flesh spongier than that of a fresh apple. Just fine for any application that involves cooking, but if you are looking for the crisp bite of an apple straight from the orchard, eat your fill now before you hit the freezer.
Like many fruits and vegetables, how you freeze them depends on how they will be used.
There are some fun peeling gadgets around and may save some time, but I tend to stick with my trusty swivel peeler. On the other hand, I can’t say enough about the value of a sturdy slicer/corer. An indispensable tool when you have a lot of apples to get through.
Once sliced, dip the apples in a bowl of water with a little lemon juice stirred in (about a tablespoon per gallon) to prevent browning.
To prevent clumping, arrange slices on a plate or baking tray lined with parchment paper and pre-freeze them for a couple of hours before bagging in an airtight container or ziploc bags.
