What are infused liquids?

Infused liquids are those that incorporate additional flavors through the introduction of seasoning, spices, and herbs. This process allows the liquid to absorb and carry the flavors, enhancing the overall taste and aroma. Common examples include herbal teas or flavored oils. The infusion process can vary in time and temperature, depending on the ingredients used and the desired intensity of flavor.

The other options do not accurately describe infused liquids. Plain liquids lack added flavors and thus do not qualify as infused. Similarly, liquids containing only water and sugar or those that have been frozen for preservation do not involve the flavor enhancement characteristic of infusion.
