Roman Punch is a very easy-to-make cocktail. All you need is some lemonade, orange juice, rum, Champagne, and ice. Simply combine all the ingredients in a glass, stir, and enjoy.
In a punch bowl, combine lemonade, orange juice, Champagne, and rum. Allow the drink mixture to chill for about half an hour.
Whip the egg whites and lemon juice in a medium bowl until soft peaks form. Then, gradually beat in the confectioners' sugar in the whipped egg whites.
Pour the prepared punch mixture into the ice-filled punch glass. Top with a dollop of meringue, and mix using cocktail stirrers. Your Roman punch cocktail is ready!
