Originally born in Cuba in 19 10, several pieces of fresh mint leaves were sprinkled with a little sugar, and a few drops of fresh lemon juice were squeezed. The above materials were mashed with a stick, then soda water was poured in, and then rum was poured in. Finally, ice cubes were added and stirred gently, and a cup of refreshing drink with the crisp sound of ice cubes, cool mint flavor and freezing was made.
