Atleast an hour before serving the cocktail put the cocktail glass or the champagne flute inside a freezer so it becomes fully chilled when the cocktail is served.
Fill the shaker with some ice cubes that have already been crushed. Now start adding all the ingredients one by one into the shaker.
Gently shake or stir all the ingredients together such that they are perfectly mixed with each, including the ice.
Take the cocktail glass out of the freezer. Carefully strain the prepared cocktail mixture into the glass.
The Prince of Wales Cocktail is now ready. It is ideally served in a Champagne flute. The process can be repeated according to the number of servings.
