After searching for something to do with this thing, I settled on making Limoncello, the Italian Lemon Liqueur. It has been steeping in vodka the last 45 days. This weekend I strained off the lemon peel and added sugar syrup. It is now supposed to age for some more, but there was about six oz. that wouldn't fit back in the bottle, so we had a taste. It was delicious. When I get back from JA it should be good to go.
I've been thinking of making Limoncello with rum. I made one attempt but it wasn't so good. I think I'm going to use overproof rum next time.
Limoncello is most often kept in the freezer and served by the shot chilled. Many Italian restaurants make their own. Try it sometime.
