-Well, there are all sorts of sauces used for enchiladas-ranchera, tomatillo, red chile based, and various moles. I really haven't encountered ketchup consistency sauces-I guess if you had a plate of mole enchiladas that was under a heat lamp too long. There is also a style called "enchiladas a la plaza" where the tortillas are dipped in a red chile sauce and fried-so that they are not "wet" at all-this is very traditional. Also a black bean sauce covered ench-"enfrijoladas".
-I guess I'm still confused about this Chicago-style thing. Not sure what kind of sauce, and where they are serving this stuff.
-My biggest complaint since the 70's is that the moles used are too often from a jar, and that too much emphasis is put on "Suiza" style (covered in soupy sauce and cheese). (Allright, that's not my biggest complaint since the 70's)
-Have you tried some of our upscale places?-Frontera rotates enchiladas from the various regions on their menu. Salpicon, Adobo, Geno's new place, all may have good versions. I'm not a big ench fan anymore, so can't say for certain...
I love animals...they're delicious!
