The sauce is built almost entirely from dried chiles blended with little else, which is what gives it a deep red color and a heat that's meant to genuinely burn, living up to the 'devil' name.
Shrimp are sautéed in a fiery sauce of blended chiles de árbol, garlic, and tomato until they turn deep red, then served sizzling with rice, tortillas, or piled onto a tostada. Seafood stands along Baja's coast, from Ensenada to Tijuana, serve it as one of the spicier options on the menu.
