In the preparation of a Grande hot chocolate, how many additional pumps of mocha sauce are added compared to a Tall?

When preparing a Grande hot chocolate, the standard recipe includes more mocha sauce than a Tall size due to the larger volume of the drink. A Tall hot chocolate typically has two pumps of mocha sauce, while a Grande hot chocolate includes three pumps. This means that when transitioning from a Tall to a Grande, an additional pump of mocha sauce is added to maintain the flavor balance appropriate for the increased drink size.

This method of scaling up ingredients helps ensure that the richness and sweetness of the hot chocolate remain consistent with the drink's intended flavor profile across different sizes. Thus, the correct answer reflects this incremental increase in the number of pumps used for a Grande compared to a Tall.
