Like most New Yorkers -- natives, transplants, whomever -- we love bagels. We love bagels so much that we did a whole episode on them last season. But we didn't quite capture the essence of this city’s bagel identity. So we're calling for a do-over. On our season finale of Food/Groups, we take on New York City's bagels (again) and this time we're diving into the history of smoked salmon, or lox, which has become a key food item to the NYC bagel tradition.
