Once we got the dehydrator out we have become dehydrating machines, dehydrating everything we have in the house that we think would be good. Including apple slices.
To prevent any browning of your apple slices fill up a large bowl about halfway and add a splash of lemon juice. This is completely optional of course.
As you core and slice your apples put the slices into the bowl of lemon water. Again, this is optional to prevent any browning. Alternatively you could place them directly onto your dehydrator trays.
You can “over” dehydrate them to where they are dried out and snap when you try to bend them. Personally, I really enjoy them like this, they are super sweet and crispy.
