Directions

1. Place an 8-quart stockpot over medium heat; add oil. When oil is hot, and add flour. Using a wooden spoon, stir oil and flour together to form a roux, and cook until it becomes the color of milk chocolate, 20 to 25 minutes. Add onions, bell peppers, and celery; stir until well combined, about 5 minutes. Add garlic, cook for 30 seconds. Add beer and shrimp stock; season with thyme, bay leaves, crabs, Worcestershire, salt, and cayenne. Bring gumbo to a boil, and immediately reduce heat to a simmer. Let gumbo cook, simmering, about 1 hour, skimming surface occasionally.
2. Season shrimp and fish fillets with Emeril's Essence. Add to gumbo and stir to combine; cook for 2 minutes. Add oysters, and cook, stirring often, about 5 minutes.
3. Serve gumbo garnished with parsley, scallion tops, and file powder in shallow bowls over white rice.
