Again, first attempt and was, in my humble opinion, greatly successful. So much so that the pictured beverage was my third made and consumed.
50ml Bacardi Carta Blanca
Dash of sugar syrup
Booze, lime, mint and syrup (or just 1/2 teaspoon of sugar) into bottom of a hi ball glass, muddled, crushed ice thrown in and mixed about. Topped up with soda and garnished with a lime wheel and mint sprig.
