Definition & Meaning of "sugar cube"

What is a "sugar cube"?

A sugar cube is a small, compressed block of granulated sugar, typically in the shape of a cube, although other shapes are also available. These cubes are commonly used to sweeten hot beverages such as tea and coffee. Due to their compact size and uniform shape, sugar cubes dissolve slowly when added to hot liquids, allowing for gradual sweetening of the drink. They are convenient for portion control and are often found in cafes, restaurants, and households where hot beverages are served. Additionally, sugar cubes can add a decorative touch to tea and coffee presentations, enhancing the overall drinking experience.
