Which term is used to describe blended drinks made with sugar-free, caffeine-free, or dairy-free options?

The term "Carburetor" specifically refers to a type of blended drink that is made with various customizations, such as sugar-free, caffeine-free, and dairy-free options. It aligns with the idea of creating a personalized beverage that caters to individual dietary preferences or restrictions. This makes it a suitable choice when discussing blended drinks that offer flexibility in ingredients.

While "Blender" could imply the method of preparation, it does not specifically relate to the customization of the ingredients themselves. "Smoothie" and "Frappuccino" are more associated with specific styles of blended drinks, which do not explicitly highlight the aspect of customization with sugar-free or dairy-free components as prominently as "Carburetor" does. Thus, “Carburetor” is the most accurate term to describe those blended drinks tailored to individual dietary needs.
