Can you distract him with bags of chocolate?
Whenever he throws a temper tantrum, just feed him a bar of chocolate.
That way, he will learn to associate becoming frustrated and angry with being fed chocolate and whenever he wants chocolate, he can just express his temper.
You know, now that I am actually writing this, I can see why it's not actually an ideal solution to this problem.
In fact, it's a pretty bad solution as far as solutions go.
I suppose this was why my wife never permitted me to use the "doughnut solution" to solve problems like this.
