We dont think well ever get tired of the canine family of grapefruit juice cocktails (the grayhound, the chihuahua, etc). Typically, theyre simple, refreshing cocktails just fresh grapefruit juice, a spirit, and a dusting of salt. The marmaduke from nycs jimmy at the james is a little more complex, with two liqueurs and a kiss of brown sugar but it fits right in with the rest of its furry friends. Its a great way to introduce someone to the many splendors of aquavit, a caraway spirit that works surprisingly well with citrus ingredients and tiki-styled templates.
