2 shots White Creme de Menthe
1 glass Ginger ale, Tonic or Soda
Put double of Creme de Menthe in a 10-12 oz (300-350ml) glass and fill to top with Ginger Ale, Tonic, or Soda Water.
Tastes like mouthwash! (For Americans, think of mint flavored Zima (For others, Zima is a malt beverage that tastes like alcoholic soda))
