Now you really got me with this one - I have to admit that eggplant was never among my favorites until some years ago I tried the Chinese eggplant sautee at a nice Chinese restaurant. From then on eggplant recipes are something I always look forward to.
I guess I will go to some specialized stores to find some of the Asian products like the mustard powder, pork sung and 5 spice. I think they also put pork sung in the sauteed eggplant, even though I am not sure what kind of pork this is, I only know it is fried. As for the hoisin sauce, I have this at home already so at least I am safe with this one.
Will let you know if I can find the products. Also I will put this under the vietnamese child forum. Thanks for sharing!
