Cranberry Moonshine may not always be available in the liquor stores, but it's easy enough to make your own. Simply pour unflavored vodka (or unflavored grain alcohol, for a stronger result) into an airtight glass container, add a handful of fresh cranberries, and store in a dark, room temperature area for any length of time but at least a couple of hours.
Use as much vodka as you want to infuse. We filled a mason jar with 2 cups.
The longer you let the berries steep, the more flavor will be extracted. If you have the patience, carefully puncture each berry with a small fork to help the process along.
