An improved method of serving a slushy drink is provided wherein a manufactured slush is filled into a container (I) to occupy at least 70% of the volume of the container and then hardened to produce a frozen product in the container. The frozen product is then transported through a cold chain to a retail outlet. Following warming to a temperature of between -14 and -5.degree. C., the frozen product is transformed into the slushy drink, preferably by deforming the container.
