Christmas Eve in Naples is all about fish and lots of it. While this whole concept of seven fish seems to be distinctly and Italian American thing, we do eat fish in its myriad forms on Christmas Eve. The logic for this being that we should be abstaining from meat to recall the birth of Jesus. Obviously gavaging ourselves with 15 kilos of seafood should really do the trick.
The most common dishes on Christmas Eve often include antipasti of marinated and fried fish, kelp fritter and maybe just a touch of good mozzarella (Although not all on the same plate. Fish + Cheese = BAD in Italy). For primi we often have Spaghetti all Vongole (Spaghetti with Clams) or Risotto al Pescatore (Seafood Risotto).
For main dishes or secondi, we enjoy fish both baked and fried. Generally we bake Orata, Brazino or Spigola (Sea Bass) aqua pazza style with tomatoes, parsley, garlic and olive oil. And then comes the fried fish. After soaking salt cod for days, we pat, flour and deep fry.
