Abstract: A method of packaging and preparing a mixed drink and the mixed drink mixer package therefor, wherein pre-measured mixer ingredients are packaged in a container that is marketed and sold with extra head-space for the subsequent addition and shaking of ingredients according to the consumer's taste, and preferably with a strainer for straining the mixed drink prior to serving. The consumer may prepare the drink by adding an alcoholic beverage and, if desired, ice through the wide opening of the container. Blending of the ingredients may be accomplished by shaking the container, which is provided with a removable, leak-proof cap. The ingredients may be strained through the detachable strainer when they are poured from the container, or the container itself may be used as a drinking vessel, thus minimizing the time, effort, and inconvenience of amassing a variety of containers and implements that are associated with prior art methods of packaging the ingredients for mixed drinks and preparing mixed drinks.
