Start the process by adding crushed ice in a cocktail shaker and then the remaining ingredients one by one. If a cocktail shaker is not obtainable, then an electric blender can also do the job but make sure you do not blend the drink too much.
Shake it until all the ingredients combine with each other and the ice melts to add the required chill to your drink. Do not add a great amount of ice, however, because it will ruin the flavor of your drink and result in a watery mixture rather than a Brass Monkey cocktail
Pour the drink in a highball glass and garnish it with orange wedges.
