Anyone have a reliable recipe for Moo Shu pancakes, like these in the upper right-hand corner:

I can't evaluate the (very different) ones I see online.

I'd prefer not to have to make 10 versions before I find one that's close to authentic.

The first try was a bust: http://www.epicurious.com/recipes/food/views/Moo-Shu-Pork-243065 [1]

(I have several Asian markets at my disposal, so maybe I can find them pre-made. Alas, everytime I try to find something in an Asian market, it's like taking a trip (in every sense of that word) down the rabbit hole in Alice in Wonderland. They find me a few days later lost and crying next to the dried shrimp, item thoroughly searched for but unfound.)
