A combination pitcher and mixing subassembly is described that incorporates a mixing head which is longitudinally reciprocally movable within the pitcher. The combination is particularly well suited for use with pitchers that are not cross-sectionally circular, such as pitchers that are elliptical or that have parallel; elongated side walls with semi-circular ends. The mixing head has a peripheral region which generally conforms to the internal bottom configuration of the pitcher. The mixing head has a plurality of straight, elongated vanes that extend across the mixing head in parallel, spaced, diagonal relationship to each other with the vanes on one side of the mixing head shaft being inclined at an opposite angle relative to those on the other side of the shaft. Preferably, the mixing head also has a plurality of vertically oriented, spaced, parallel baffle plates that extend across the mixing head perpendicularly relative to the vanes and that join the vanes at all locations of cross-over.
