Tips for making the Grapefruit Cosmo:
  • If you are going to squeeze your own grapefruit, make sure you use ruby red grapefruit
  • Slice the garnish different ways, experiment with a grapefruit wheel, a wedge or a chunk
  • If you can’t afford premium ingredients, it’s okay to use mid-level as with the robust flavor of the grapefruit, you won’t notice the difference
  • Shake vigorously so the ice breaks off in slivers.  There is nothing like little ice chips floating in your drink
