True or False: When there is a fruit syrup in a hot drink, you keep it in the cup.

The correct answer is that you do not keep fruit syrup in a hot drink. This practice is based on the nature of fruit syrups and how they react to heat. In hot beverages, fruit syrups can curdle or alter the flavor profile when combined with high temperatures, potentially resulting in an undesirable taste or texture. Therefore, it is standard practice to omit fruit syrup from hot drinks to maintain the intended quality and flavor.

In the context of this question, the other options suggest various conditions under which fruit syrup might be allowed in hot drinks. However, none of those conditions align with the best practices in beverage preparation for hot drinks, where preserving the quality and flavor integrity is paramount.
