Pomegranate-lime vodka for... well, because you can!
You'll need pomegranate arils from a medium-sized fruit (pith and rind discarded) and crush them slightly with a rolling pin. Along with this, add thin strips of zest from a medium-sized lime to 1½ cups of vodka (Skyy, Svedka, or Absolut), and let this mixture stand in a 1½-quart airtight jar for a good 14 days. Shake every third day and then strain to use.
