Final answer:
False. Tom-tomming is not necessary for non-carbonated iced drinks.
Step-by-step explanation:
False. Tom-tomming (pouring back and forth) is not necessary for iced drinks that are not carbonated. Carbonated beverages, like soda or sparkling water, should be poured back and forth to ensure they are well-mixed and to minimize the amount of carbonation lost when opening the container. However, non-carbonated iced drinks, such as fruit juice or iced tea, do not require tom-tomming because they do not have dissolved gas that needs to be evenly distributed.
