1. A stirring wand configured for selective engagement with a mixing device, the stirring wand comprising:
a substantially vertical portion having an upper end and a lower end, the substantially vertical portion being positioned entirely outside of a rotational axis of the stirring wand;
a first tapered surface that defines a portion of a continuous surface that transitions from a first pitch angle proximate the upper end of the substantially vertical portion to a second pitch angle proximate the lower end of the substantially vertical portion, wherein the first pitch angle is different than the second pitch angle;
a substantially horizontal portion having a base and a distal tip, wherein the lower end of the substantially vertical portion and the base of the substantially horizontal portion define a continuous chamfered surface, and wherein the base is positioned below the lower end of the substantially vertical portion; and
a second tapered surface extending from the base to the distal tip and defining another portion of the continuous surface that transitions from a third pitch angle proximate the base to a fourth pitch angle proximate the distal tip, and wherein the third pitch angle is different than the fourth pitch angle.
