Adobo is a Spanish marinade that includes paprika, oregano and some kind of acid, usually vinegar. The flavor of the adobo sauce words well with the cod.
Combine the oil, lemon juice, paprika, oregano, cumin, salt and pepper in small bowl. Using a basting brush, spread the mixture on both sides of the fish. Place the fish in a pie plate, then cover and refrigerate for 20 minutes.
Preheat the broiler.
Place the fish on a rack in a broiler proof baking pan. Broil 3 inches from the heat for 5-7 minutes or until the fish just begins to flake when tested with a fork.
