How to Prepare a Manhattan
The Manhattan should be prepared by stirring. Shaking the combination of ingredients produces a drink that is cloudy and foams across the top. Stirring preserves a transparent drink and allows the consumer visual as well as gastronomic pleasure...
The preference for stirring is based on the size of the ice used and the dilution desired: the larger the ice, the slower the dilution; the smaller the ice, the faster the dilution. Ultimately, drinkers need to know how much dilution they want in their Manhattan.
