This summer, I saw the Greenhook Beach Plum Gin Liqeur on sale on the eastern end of Long Island and was intrigued. Did some online research and stayed intrigued. I've never experimented with sloe gin, or with the Averell damson gin liqueur. Now I'm just back from a trip to NYC with a bottle of the Greenhook. I'd welcome suggestions for using it in cocktails from those who've tried it or its cousins.
