Sear the cod fillets in the bacon drippings first to get a good crust; then add back to the pan, and cover so they can steam and impart their juices to the vegetable mixture. You can also use grouper or snapper.
Crispy Cod Cooked 'Unilaterally' with Creamed Leeks
You just put it in a hot pan, and don't move it until it's cooked all the way through. What that means for this cod is one side develops a thick, golden, perfect crust, and the other side is steamed to flaky perfection. I've combined the vegetable and the sauce into one, serving the fish on a bed of simply creamed leeks. Soft and subtle and lovely.
Cod in Creamy al Ajillo Sauce over Cilantro Lime Brown Rice served with steamed Brussel Sprouts or Brocolli. Poor Sauce over fish/rice and vegatable. I added lime juice to the mixture once cooked. Yummy!
