It's almost summer in New York, which means walking and bicycling, active city parks, and lots of hungry tourists. Despite the phenomenal explosion in popularity of the food truck in the past few years, the most ubiquitous New York street food is still the dirty-water dog: a frankfurter that's been boiled in a steaming puddle of old water and meat grease and then served in a flaccid bun. It's not that the dirty-water dog can't hit the spot — when you're on the sidewalk and just gotta eat, the weiner itself, oftentimes a natural-casing Sabrett beef dog, isn't a terrible product. But frank-ly speaking, my kid, who at 11 years old is hungry all the time, thinks they're gross.
