SEAFOOD GUMBO

Steps:

• Cook bacon in a 10-inch heavy skillet (preferably cast-iron) over medium heat until browned but not crisp. Transfer bacon to a bowl with a slotted spoon and transfer rendered fat to a heatproof liquid measure, then add enough oil to fat to bring total to 3/4 cup.
• Stir together fat and flour in skillet with a wooden spoon, then cook roux over medium-low heat, stirring constantly, until well browned (a shade darker than peanut butter), about 20 minutes.
• Add celery, bell pepper, onion, and garlic and cook, stirring occasionally, until vegetables are tender, about 15 minutes. Transfer to a 6- to 7-quart pot.
• Stir in stock, tomatoes, okra, thyme, bay leaf, cayenne, and 2 teaspoons salt and briskly simmer, uncovered, stirring occasionally, until vegetables are very tender, about 30 minutes.
• Add parsley, scallions, shrimp, and oysters with their liquor and cook, stirring, until seafood is just cooked through, about 5 minutes.
• Stir in crabmeat and bacon and simmer until heated through, about 1 minute. Season with salt. Discard bay leaf.
