Shiver me timbers, they changed their formula. I don't know exactly when this happened since I buy the huge bulk cannister and it had therefore been awhile since I purchased my last batch. They did change it though.
It used to not dissolve all the way leaving little chunks of powder and giving the chocolate milk a bit of a grainy texture.
I loved that part!
Now it dissolves all the way, so it has the same texture as chocolate milk made with syrup and there is no "happy ending" at the bottom of each glass.
Oh well, I still like the stuff, just not quite as much.
