With its carne, corn, and nopales, Tucson’s cuisine reflects the influence of the northwestern Mexican state of Sonora, which shares a border with Arizona. What’s more, much of what we now know as Sonoran fare, including chimichangas and air-dried carne seca, was created or popularized in Tucson. The city’s position as a culinary crossroads is nowhere more apparent than along the south side’s 12th Avenue, a bazaar of fruit stands, bakeries, and diners serving the flamboyant Sonoran hot dog, which originated in the mid-20th century in Hermosillo, the capital of Sonora.
