Variation To make this dish without a trip to the fish market, substitute two six-ounce cans of drained tuna for the cod. Stir it into the tomato sauce and warm for about a minute before tossing with the pasta.
Test-Kitchen Tip To peel the fresh tomato quickly, make double use of the pasta-cooking water. Bring a pot of water to a boil, core the tomato, and drop it into the water for fifteen seconds. Using a slotted spoon, remove the tomato from the water, peel, and chop it. Then you've got boiling water ready for the pasta.
The adage is white wine with fish, but the tomatoes in this sauce call for a red instead. Try a sprightly Lago di Caldero or an easier-to-find Valpolicella.
