In order to make a tom collins drink, you will need 2 ounces of gin, 1 ounce of lemon juice, 1 teaspoon super fine sugar, 3 ounces club soda, 1 maraschino cherry and 1 orange slice. In a tumbler half-filled with ice, mix the gin, lemon juice and sugar. Shake well, strain and pour into a glass half-full of ice. Add the club soda, cherry and orange slice. Bottoms up!
