1.5 parts pomegranate juice
a couple mint leaves, crushed or muddled
.5 part lime juice
1 part limoncello
1 part vodka (can substitute applejack if you also tweak the juices upwards)
2 parts water
.5 part simple syrup
this is not a concentrate, but it's strong; may need a bit more water depending on your tastes. excellent over a ton of crushed ice, still tasty even when the ice has mostly melted.
