After a long long time I had chocolate milk today. I wondered - what is the best way to make it - put the chocolate powder first, or the milk first, or a combination of the two?

I put the chocolate first today, and there was so much chocolate stuck at the bottom.

On the other hand, if I put chocolate later, I have to make sure it does not become chunky, and dissolves properly.

Is chocolate milk worth the time, to put some milk and then some chocolate, and then some more milk and so on?
