This simple syrup can be used in all kinds of drinks that call for simple syrup. I was inspired when I saw a recipe for muddled basil and gin with simple syrup. I got a costco-sized bottle of store-brand gin a few months back and it's laid untouched ever since. I had a party to go to, so it was a great excuse to get back into the kitchen and cook up something using the rosemary I had growing in my little garden. I ended up making a drink that was about equal parts gin and simple syrup plus fresh lemon juice, shaken with ice and served with a sprig of rosemary over ice. This syrup makes great herby summer cocktails, and other aromatic herbs can substituted for the rosemary (like thyme or sage). I would encourage you to make a double or triple batch, as this ran out mighty fast.
