What is the size option for cortadito?

The correct answer is based on the traditional serving sizes associated with cortadito, which is a popular Cuban coffee beverage. Cortadito is typically served in smaller portions, reflecting its strong coffee flavor balanced with milk. The size options being either single or double encapsulate the common practice of serving espresso-based drinks, where a single shot provides a more concentrated flavor, while a double shot offers a stronger coffee experience.

In contrast, other choices reflect size options that are not typically used for cortaditos. Options like regular or large, small or medium, and large or extra-large suggest a more general beverage sizing that is not characteristic of this specific drink. The focus on single or double for cortadito highlights its commercial and cultural significance, where the emphasis is on espresso strength rather than mere volume.
