What is the final step in preparing the Pink Squirrel cocktail after mixing the ingredients?

The final step in preparing the Pink Squirrel cocktail is to strain the mixture into a Martini glass. This method ensures that any ice or solid ingredients from the mixing process are removed, resulting in a smooth and visually appealing drink. The Pink Squirrel is known for its creamy texture and smooth appearance, making the straining crucial to achieve the desired consistency.

Straining allows the cocktail to maintain its intended flavor profile while providing an elegant presentation in a Martini glass. This step is particularly important for cocktails that incorporate cream or other ingredients that can alter the clarity if not strained properly. Serving the drink in a clean glass elevates the overall experience for the customer, aligning with the refinement often associated with classic cocktails.

Using a different method, such as serving over ice, would change the drink's concept significantly. Similarly, garnishing or blending, while important parts of cocktail preparation at different stages, do not come after the mixing process in the context of the Pink Squirrel. Thus, straining into a Martini glass is the correct final step to complete this cocktail accurately.
