No home bartender disputes the importance of a quality shaker. Opaque cocktail ingredients like cream, fruit juice, and egg whites need to be shaken hard to be incorporated into a drink. It provides a light, delicate experience; a cocktail full of tiny air bubbles that dance on the tongue. Well, that shaker alone won't do a ton of good for cocktails made with clear ingredients. Drinks like Manhattans, Negronis, and Martinis should be ice cold, crystal clear, and have a good deal of richness, heft and weight on the palate. To achieve that, they must be stirred, which means you've got to have a quality bar spoon.
