The Ghost-tini is one of a number of specialty Halloween cocktails that are creamy, candy-like creations -- but this one takes the cake.
The drink begins like many dessert-worthy cocktails with a luscious Irish cream, in this case, Bailey's with caramel, and a vanilla vodka, though it is the pumpkin liqueur addition that grabs attention. It is that ingredient that transformed this drink into a pumpkin pie in a glass and the cookie rim and candy garnish are a bonus that turns this into an adult treat with a hint of childhood.
It is not recommended to add dry ice directly to cocktails (use it as a party favor for its fog effect instead) because if someone accidentally ingests it, it can be very harmful. There have been a number of stories in the news about drinkers 'unknowingly' or mistakenly ingesting dry ice and burning their internal organs. Make the decision based on your guests and their level of intoxication.
