What is the primary non-alcoholic mixer in Dangerous Waters?

The primary non-alcoholic mixer in Dangerous Waters is pineapple juice. This choice is correct because pineapple juice typically contributes a significant flavor profile that enhances the drink's tropical theme. It adds both sweetness and acidity, which can balance the other components of the cocktail.

Pineapple juice is commonly used in a variety of cocktails and non-alcoholic beverages because of its refreshing and vibrant taste. It complements other mixers well, creating a well-rounded drink that appeals to a broad audience.

While fresh sour, strawberry puree, and coconut cream are all delicious mixers that can be found in various cocktails, they do not serve as the main non-alcoholic component in this particular drink recipe. Fresh sour might provide tartness, strawberry puree adds fruitiness, and coconut cream lends a creamy texture, but pineapple juice is the star mixer that defines the Dangerous Waters experience.
