What should be added to the mixing tin before straining in a Jamaican Mai Tai?

In the preparation of a Jamaican Mai Tai, ginger beer plays a crucial role in enhancing the cocktail's flavor profile. When mixing this drink, ginger beer is added to the mixing tin to contribute a spicy and sweet effervescence that complements the rum and other ingredients. This addition is not only significant for taste but also for the overall texture and refreshment of the drink.

The alternative choices—ice, a pineapple slice, and the option for none—do not serve the same purpose. Ice is generally used in the mixing or chilling process and would not be something to strain. A pineapple slice typically serves as a garnish rather than an ingredient to be mixed, while "none of the above" does not acknowledge the essential component that ginger beer brings to the cocktail. Therefore, adding ginger beer to the mixing tin is the correct action prior to straining, as it helps create the desired flavor balance in a Jamaican Mai Tai.
