The recipe behind the signature taco of this Broadway Road food truck, the tacos ahogadas, took co-owner Alma Kerby 10 years to perfect. Three taquitos shaped like rolled-tortilla cigars submerge in a thin tomato broth peppered with jalapeno. Melted cheddar clings to the yellow lengths. The broth is nimbler and more refreshing than heavy, and the tacos have a nice, not-yet-sogged crisp that gives way to decadent beef inside. The Drowning Taco, both the business and the dish, are a nice addition to the local truck scene. So, too, are the more standard flour tortilla tacos, packed with the likes of creamy cabeza and char-tipped carne asada, all lavishly topped with cilantro and an avocado-based salsa.
