Which of the following describes a characteristic of shaved ice?

Shaved ice is created using an auger, which is a device that helps shave blocks of ice into a fine, fluffy texture. This method allows for a delicate consistency, which is ideal for serving with flavored syrups. The auger rotates and scrapes the ice, producing shavings that resemble snow.

When it comes to the other described methods or characteristics, shaved ice does not involve a compression method, as that would typically result in a denser, compact form of ice, unlike the light and airy texture of shaved ice. Additionally, shaved ice is not served in solid blocks; instead, it is often served as a mound of shavings in a cup or bowl. Lastly, while freezing water into sheets may relate to other forms of ice, it does not pertain to the method of creating shaved ice, which focuses on shaving, not solid freezing. Thus, the use of an auger is the defining and correct characteristic of how shaved ice is produced.
