Mojitos

and mash the mint with a spoon to bruise the leaves and release the flavor.
   
  Add:
1 - 2 t fresh lime juice
2 oz light rum
a splash of sparkling water
  ice
   
  Stir and taste.  If satisfied with the proportions, make another one for your friend.
Notes & Variations:

  2. Use a large sprig of fresh mint, stem and all.
