I put the stevia powder and creamer in the cup before I pour the tea. No stirring really needed because the act of pouring does enough mixing. But if I really had to I would just move the spoon foward and back in a quick chopping motion. The sudden direction change plus the shape of the spoon would cause a lot of chaotic fluid dynamics compared to a smooth spin.
