Like a james bond martini . . .
. . . it should be shaken, not stirred. that is if the grittiness some complain about bothers you. put a scoop along with your preferred liquid -- i recommend a blend of blueberry, pomegranate, tart red cherry and cranberry juices (all 100%) -- in a sealed container and shake the hell out of it. you'll get a much smoother blend than you can with stirring.
