Mere mention of a "soup dumpling" sighting is often enough to make a serious adventure diner twitch, activating a primal tracker instinct more commonly reserved for tasks like pursuing the ivory-billed woodpecker.
Exceedingly uncommon around here, and even rarer done well, this Shanghai treat is a sleight of broth and dough that puts the "soup" inside a steam-puffed beggar's purse twisted up tight and tidy.
This curiosity (usually noted as "Shanghai steamed buns" on menus) has long incited road-trip quests, most often to New York's Chinatown, where Joe's Shanghai is among those that made them famous. And the first question is inevitably: How did the broth find its way inside to begin with? The second, and perhaps more pressing dilemma, though, is how to eat the equivalent of a boiling-hot broth balloon without getting scalded in the process.
