Per martini:

3 blackberries

Dash of sugar

3 drops liquid smoke

2 - 3 ounces vanilla vodka

Place blackberries in a small bowl.  Sprinkle with sugar and put a drop of liquid smoke on each berry.  Mash lightly with the back of a spoon to release some of the juices without breaking apart the berries.  Place in the bottom of a martini glass.  Pour vodka over a few ice cubes in a martini shaker and shake a few times until chilled.  Pour vodka over berries and enjoy!
