This cocktail is comprised of a homemade rosemary simple syrup, whiskey and my favorite: hard apple cider! I think hard apple cider is an amazing secret weapon when making fall cocktails!
To make rosemary simple syrup, bring 1 cup of water and 1 cup of sugar to a simmer. Remove from heat and add in three 5-inch rosemary sprigs. Steep for 20 minutes and strain mixture into a jar.
