To me a proper one is very simple to make, but it takes some preparation and some right tools to get the job done right.
First get a silver cup. You will need this to make your drink ice cold and refreshing. It doesn't get any better than this. Second use crushed ice to give your drink a frosty kick and feel. Third gently muddled your mint inside the cup without dangerously bruising it or making a salad, and finally pick a good bourbon you like.
It's really that simple. Enjoy bourbon whiskey on this day it is a great time to be doing it, and no cocktail is more fitting for such a time. To learn more watch the video below. Cheers!
