Blended beverage A frozen or semi-frozen ingredient is pre-packed in a drinks vessel at a packing location. The pre-packed drinks vessel is then transported to a dispensing location remote from said packing location. Liquid is poured into the drinks vessel at said dispensing location and blended with the frozen or semi-frozen ingredient. The drinks vessel defines a chamber in which the frozen or semi-frozen ingredient is packed at the packing location, the chamber having a base and a side wall extending up from the base. The frozen or semi-frozen ingredient is packed in said chamber in such a manner as to define a spacing between said frozen or semi-frozen ingredient and said side wall, into which the liquid ingredient may flow when added at the dispensing location.
