What happens when salt is mixed into hot chocolate?

Adding salt to hot chocolate is a personal preference, but in general, salt can enhance the flavor of the chocolate by bringing out the sweet and bitter notes. It can help balance the taste and reduce the sweetness of the drink, creating a more complex flavor profile. However, the amount of salt added should be adjusted according to personal taste, as too much salt can overpower the chocolate flavor. Some people also add salt on top of whipped cream in hot chocolate, which creates a contrast between the salty and creamy flavors.
