I would like to make for  my book club a lemon drop cocktail.  The recipe I would like to use - only uses freshly squeezed lemon juice, sugar and vodka. My dilemma  though  is as there are nine of us -I don't really want to use a cocktail shaker three times  (as the host I have a few other things to do). Could I use a blender? If so at what point would I add the ice?  Thanks so much for any help.
