I'm one of those people who appreciates a good cocktail, but always has a hard time remembering how to make even the most classic of libations. After years of constantly pulling up recipes to figure out how to make something as simple as a martini, I finally found a solution to my problem: a Dial-A-Drink cocktail shaker. This multifunctional gem is perfect for holiday entertaining: just turn the base to your desired cocktail (this version includes classics like margaritas, whiskey sours, cosmopolitans, side cars, mai tais, old fashioneds, and more) and follow the instructions right on the shaker.
