The apparatus comprises a container and a mixing device located in the container. The container has an inner surface defining an inner volume capable of holding a quantity of liquid and powder. In one embodiment the mixing device has a surface, wherein the surface defines a plurality of apertures; the plurality of apertures define a grill through which the liquid and powder can pass through and thereby mix together. In another embodiment the mixing device defines a multiple number of strands of stainless steel through which the liquid and powder can pass through and thereby mix together. In a further embodiment a method is provided for mixing a powder and liquid combination comprising the step of shaking the container to induce the liquid and powder to pass through the grill.
