The Rum Flip is a classic cocktail with origins dating back to the 17th century. Originally made with ale, sugar, and a whole egg, this rich and velvety drink evolved into the spirit-based version we know today. Using dark rum, warm spices, and a luscious egg, this cocktail is a perfect blend of deep, caramelized sweetness and creamy texture, making it an excellent nightcap or a luxurious holiday treat.
