Bill,
Looks delicious, although very non-trad.
I've had chiles rellenos in a variety of forms, from very omelet-like to tempura-like, and they're all good (except when they're overly greasy, and even that can be good in its own way).
I grew cuitlacoche/huitlacoche once... before I knew what it was. I'd planted about 20sf of corn in my backyard garden. Few of the stalks even developed ears (common, as corn needs a dense population for polination), and those that did developed these black, swolen fungal kernels. This was about a year before I'd even heard of huitlacoche.
I'd had better luck on another year, growing a fair amount of popcorn, but that year it was all smut. I've given up on corn since, sticking to basic salsa ingredients: tomatillos, tomatoes, chiles and cilantro.
