The local grocery chain (Rainbow) here in Minnesota carries the Seitan in
the refrigerator section of the healthy foods area. It is in either a blue
box, for the non seasoned, no fat, high protein version, and a red box for
already seasoned for stir fries low fat, high protein version.
I found the stir fry box to be a little salty tasting for myself. But have
used the regular in lots of recipes. This is most likely exactly what your
spicy mock duck was made with.
I have cut it up and used it in place of the beef or chicken in many of the
packaged Asian type mixes with great results, orange beef, hot and spicy
