Ah-ha, yes, I remember you mentioned this on your post about old-school dim sum (which I'm going to link again because I really like it).

I feel like a bit of a coward for not actually having tried making my own cheung fun yet! Maybe I'll give it a go some time, particularly since as of this week I now finally own a wok steamer.

I remember I had grilled cheung fun with XO sauce at Dragon Castle last year, but I can't remember if they were plain or not.
