Cà phê muối is a unique Vietnamese coffee drink that incorporates a small amount of salt to enhance the coffee's flavor. Originating from the city of Huế, this beverage combines the richness of strong Vietnamese coffee with the subtle, savory notes of salt, creating a distinct taste experience. The salt is often added to a layer of sweetened condensed milk at the bottom of the cup, or in a whipped creamy topping, balancing the coffee's bitterness and sweetness.
