When my parents visited briefly last week my mom brought me some fresh rosemary which I made into rosemary simple syrup. Yesterday evening I created a new cocktail using the syrup and a random smattering of things I had on hand.
1.5 oz gin
3/4 oz st germain
3/4 oz rosemary syrup
3/4 oz orange juice
shake together and strain into glass over ice, top with ginger beer and a piece of orange peel (and or a sprig of rosemary if I'd had any remaining.
It's surprisingly refreshing and the spicy herbiness paired well with a particularly juicy orange.
