👉 Baileys is a popular American cocktail that originated in Dublin, Ireland. It's often considered to be one of the most famous and iconic cocktails in the world. The drink has a creamy, buttery flavor with a hint of sweetness from the liqueur (which is made from the fermented sugar cane). Baileys is typically served at a warm temperature and garnished with a slice of lemon or a sprig of fresh mint for added flavor.
