Bayou Shrimp Creole - cooking recipe

Ingredients

2 lbs shrimp, raw, peeled and cleaned
1 1/2 tablespoons bacon grease
1 1/2 tablespoons flour
1 cup onion, finely chopped
1 green bell pepper, finely chopped
1/2 cup celery, finely chopped
14 1/2 ounces tomato sauce
16 ounces fire-roasted tomatoes
1 garlic clove, minced
1/4 cup dry white wine
2 cups shrimp stock
Tabasco sauce, to taste
2 tablespoons Worcestershire sauce
1 teaspoon sugar
salt and pepper
1/4 cup parsley, finely chopped
1/2 cup green onion, chopped

Preparation

In a large pot, heat the bacon grease and slowly add the flour, (whisking constantly so it does not burn) until the roux becomes golden brown, about 15 minutes.
Add onion, bell pepper, and celery and stir until tender, about 20 minutes.
Pour in the tomato sauce, tomatoes, and liquid from the tomatoes.
Add the garlic, Tabasco, worcestershire, sugar, salt and pepper.
Simmer 30 minutes, stirring occasionally.
Add the wine and reduce by half, another 15 minutes.
Add stock, 1/2 cup at a time, at about 15-20 minute intervals, reducing and stirring, let the vegetables really cook down.
Taste all along the way, re-season according to your tastes.
I like to cook this sauce down about 2 hours and then add the shrimp but you can add the shrimp anytime after the first hour.
As soon as the shrimp are pink, about 10 minutes, remove the pot from the heat.
Add the green onions, and parsley and serve over rice.
