Which of the following is NOT a standard component of cocktail preparation?

Heating ingredients is not a standard component of cocktail preparation. Most cocktails are served either cold, on the rocks, or at room temperature. The primary goal in cocktail-making is to enhance the flavors and present the drink in a way that is refreshing and enjoyable to the palate, which typically involves mixing, shaking, or stirring ingredients, rather than applying heat.

In contrast, measuring ingredients is crucial for ensuring the right balance of flavors and maintaining consistency across servings. Shaking to mix is a common technique used to properly combine ingredients, especially when a drink contains juices or other components that benefit from thorough mixing. Garnishing the drink, while not essential for taste, adds visual appeal and can enhance the drinking experience by adding a burst of aroma or flavor. Therefore, while measuring, shaking, and garnishing are integral to cocktail preparation, heating is generally not part of the standard process.
