This drink is basically a riff on an Old Fashioned. I came up with it for a brand collaboration with Grander Rum. Grander is aged in ex-bourbon barrels, so it has a nice aromatic hint of bourbon, which makes it perfect for a cocktail like this!
Add all ingredients to a mixing glass and stir with ice. Strain into a rocks glass over one large ice cube. Slap a sprig of rosemary on your hand then drop into drink. Gently express an orange peel over the top before adding it to the cocktail.
