Sonora is north of the Mexican state of Sinaloa, after which this little trailer is named, but the frankfurter you'll get here is a classic Sonoran hot dog: wrapped in bacon and grilled, the all-beef dog sucks in porky flavor to become nearly lascivious. The line-up of condiments is immutable: chopped tomatoes, grilled onions, yellow mustard, a green ribbon of hot jalapeno sauce, and a luxurious web of mayonnaise. On the side, as with every Sonoran hot dog, you get a roasted guero pepper, which is like a light-skinned jalapeno.
