The Times online has an enormous list of Favored Thanksgiving items classified by state. Louisiana's leaders are mirliton casserole and Spinach Madeline and, of course, turkey gumbo (although this last is most often a left-over item in my experience).
Most of these are predictable: wild rice casserole for Minnesota, for instance, although the appearance of stuffed artichoke on New York's list of favorites surprised me.Around here? Sure (and almost particular to New Orleans..I don't see them outside that much). But I have done a lot of my growing up in and around New York and I don't recall seeing more than a half dozen up there, either made by myself or someone who was Sicilian. Of course, they have a track record in France, too.
