Nowhere is the renowned oxymoron of "jumbo shrimp" more pronounced than at the Smoke House Market, where, for a price (twentysomething bucks a pound), you can take home a smoked, usually maple-glazed version that for all intents and purposes could be mistaken for small lobster tails. If you're flush, get a whole pound and indulge yourself (and a friend); even two or three of these gargantuans of the deep make for a completely memorable appetizer or light entrée
