Pomegranate Margarita

Back when I lived in NYC, one of my favorite haunts specialized in frozen Pomegranate Margaritas. They became a touchstone for a period in my early 20s that I haven't had the opportunity to revisit in years. But this last week I bought a cup of pomegranate seeds to eat and discovered that they fermented faster than I could consume them. So, here I am, unsure what to do with a bunch of partially fermented pomegranate seeds when it occurs to me: these would be great in a cocktail!
