A Rosemary Cocktail

We found this cocktail on a blog, Cup of Jo, and we decided to give it a try.  We found it delicious and refreshing.  The secret is rosemary simple syrup.  You make this by boiling a cup of sugar into a cup of water along with some fresh rosemary leaves.  Mix some lemon juice, about a cup of vodka or gin, and the rosemary simple syrup with a bottle of Prosecco.  Serve cold and enjoy.
