What is the appropriate preparation method of a Manhattan served "over" ice?

The preparation method for a Manhattan served "over" ice is to stir and strain. This technique is appropriate because it ensures the cocktail is well-chilled and incorporates the ingredients seamlessly while also maintaining the clarity and texture of the drink.

Stirring the ingredients, typically bourbon or rye whiskey along with sweet vermouth and a dash of bitters, allows for a gentle mixing that preserves the drink's integrity, as shaking can introduce air and create unwanted froth or dilution. The straining process, which occurs after stirring, ensures that the finished drink is free from any ice shards or other particulates, resulting in a smooth and refined presentation.

This method aligns with traditional cocktail crafting practices, particularly for spirit-forward drinks like a Manhattan, where smoothness and clarity are essential. Other methods, such as shaking or simply pouring, could compromise the drink's quality and aesthetic, making stirring and straining the best choice in this situation.
