Since swordfish is not always stocked in American supermarkets, it’s a good idea to call ahead to find out when a shipment will be arriving and place an order. Pumpkin swordfish, tuna, haddock, and cod can all be substituted for swordfish when making this recipe. The swordfish also tastes great grilled with the sauce spooned over the top.
