First, the cocktail. I am very partial to the Chocolate Martini made with Godiva Chocolate liqueur, and it is made thusly:
1 1/2 shots Godiva® chocolate liqueur
1 1/2 shots creme de cacao
1/2 shot vodka
2 1/2 shots half-and-half
Mix all ingredients in a shaker with ice, shake and pour into a chilled cocktail glass.
