That's a legit roundup. I think I've reported on my own extended Calabrese-American family's tradition of Da Eve / La Vigilia, now two years interrupted,
maledett', but I recently was looking at pictures of the spread from the 1960s, and identified with relatives that even by then they rolled with:
Shrimp cocktail ("in good years"), Clams Casino(ish), fried calamari, fried smelts, fried baccala in red sauce, spaghetti with anchovies in olive oil, and spaghetti with anchovies in red sauce, both topped with breadcrumbs. Smoked salmon was added in the '80s. Nobody can remember the days of a fresh entree fish if ever there was one in America. Also there was Jell-O, so much Jell-O. The number of fish dishes, or distinct fish / seafood species, was not initially important in the memory of my great-aunts (which extends back to the late 30s), and it wasn't really an
abbondanza until after the War and when the central family owned a house together instead of scattered little apartments and parts of houses.
The other Sicilian-Tunisian side were sick of fish and fasting and made "couscous" with beef or lamb by manually forming pearls from Cream of Wheat, steamed in a cabbage leaf or colander over the pot of meat, which included canned tomato sauce, rutabaga, and a "frozen block of spinach." Can't picture that you're going to see that one in a restaurant.
