Chef Keenan Langlois of Publico says he’ll never forget the food stall he stumbled upon one night in Mexico, or the hot dog—one that was wrapped in bacon and loaded with toppings—that he ordered from it. So when he crafted a menu of global street cuisine for the Southie spot that opened in February, he knew he had to pay homage. The result is perrito caliente, a steamed and crisped Kayem hot dog served atop roasted poblano chilies in a griddled split-top bun, topped with finely minced bacon bits and a salsa of pineapple, jalapeno and cilantro. A zesty lime mayonnaise adds a bright finishing touch. “The lime mayo is literally Hellmann’s and lime zest and lime juice. It’s the way to go,” Langlois says. “That’s what it needed to pull it all together.”
