Martinis are in! The key to an excellent martini is to ensure that it is ice cold. The classic martini has only two ingredients--so it's important to use the best ingredients you can afford. Vermouth should be stored in the refrigerator to retain its flavor. Energetic shaking with ice coupled with some flair is vital for a smooth/silky result. Stirring produces a crystal-clear martini but it will never get as cold as a shaken martini. This is also called an "in and out martini" or "spitting the vermouth." It results in a well balanced martini every time.
