What is the method of preparation for a Rusty Nail?

The Rusty Nail is traditionally prepared by simply pouring the ingredients into a glass, making option B the correct method of preparation. This cocktail consists of Scotch whisky and Drambuie, which is a sweet Scottish liqueur. Since both ingredients are alcoholic and have complimentary flavors, there is no need to shake or blend them, which would alter their characteristics.

Pouring allows the distinct flavors of the Scotch and Drambuie to mix naturally without being over-agitated. This method is especially important because the Rusty Nail is meant to be a smooth, easy-drinking cocktail, showcasing the flavors rather than aerating them, which shaking or blending might do. Therefore, for a Rusty Nail, pouring the ingredients directly over ice in a glass preserves both the integrity of the flavors and the intended drinking experience.
