As I have absolutely no idea what differentiates Sonoran Mexican cuisine from other Mexican regions, I did some searching and found this multiyear thread:
http://chowhound.chow.com/topics/94148There seems to be a lot of conflicting opinion, but the gist of it seems to be: flour tortillas, rarely/never corn; a wide variety of wheat breads available; unusual hot dogs that make up much of the available street food; a lot of beef, rather than pork or goat, that is grilled/charred, and is rarely/never marinated; limes and lime flavors in most everything; much use of mayonnaise; chunky tomato salsas, not much green/verde or pureed red sauce; low-heat/bland chili spicing; tortas are not sandwiches in Sonora, but a variation on egg foo yung. Is this what you're seeking? Or some Arizona version of this? How do
you characterize the cuisine?
A post from October 28, 2010 on that Chow Hound page sums up:
"Sonoran style food is (not) like any other, because Sonora is not like any other state in Mexico.
Typical dishes from Sonora (at least the central and northern part) have a basic staple: beef and flour tortillas. Sonora used to be Mexico's "Wheat Basket" and Sonorans try to avoid corn tortillas. It is natural that you hear the term "Sonoran food" in Arizona (they are bordering states).
Just to make it simple... here is a list of food you can find in any household across the state.
Pinto Beans (sometimes refried with lard, powder chili, chorizo, queso fresco and jalapeno)
Machaca (dehydrated beef - pounded) not shredded stewed beef.. yikes
Carne Asada - an almost charred flank stake, seasoned with salt and sometimes beer
Carne con chile - cubed or shredded beef slowly cooked in "chile colorado" (served with FLOUR tortillas
Street foods are heavenly. Hot dogs are a must have if you ever visit Hermosillo (the state capital).
Burros Percherones (oversized carne asada burrito) made with super delicious and big "tortillas sobaqueras" (armpit tortillas)... sound gross but it's basically a paper thin flour tortilla with a diameter as big as the maker's arm.
Tacos (of everything!)
... also we do use corn tortillas but they have more of a frying purpose. (enchiladas, tacos dorados and broken in pieces mixed with eggs)
To drink.... beer, horchata, coca-cola, hibiscus flower iced tea, beer, and more beer. (really Sonorans like beer)

I was born and raised in Hermosillo, Sonora... my parents are originally from Northern Sonora, so are my grandparents and my great grandparents.... you get the idea"
