Take a beer mug and put a few ice cubes in it.
Now, pour 2 shots of Scotch whisky, 1 oz of Coca-Cola and 1 shot of pre-chilled Shochu into it.
Add 3 tablespoon of sugar into the mug and stir it gently for a few seconds, until the sugar dissolves completely.
Note: The sugar will take a few minutes to dissolves as the drink contains chilled Shochu. Therefore, make sure to keep stirring until it dissolves thoroughly.
Your Duncan Macleod Cocktail is ready. Place a straw in it and serve chilled. Enjoy!
