What is the last step in preparing a tall salted caramel hot chocolate?

In preparing a tall salted caramel hot chocolate, the last step is to sprinkle the beverage with sea salt. This final touch enhances the flavor profile of the drink, balancing the sweetness of the chocolate and caramel with a subtle salty kick, which is characteristic of the salted caramel flavor.

The other steps in the preparation process involve foundational elements like pouring the steamed milk and adding the chocolate and caramel syrups, followed by topping the drink with whipped cream and a drizzle of caramel. However, to achieve the desired flavor combination and presentation, the sea salt must be the final addition, ensuring it stands out above the whipped cream and garnishes, completing the drink's aesthetic and taste.
