In a heavy bottomed sauce pan (like an iron skillet), melt the butter over medium-high heat. Next, whisk in the flour to form a roux. Continue whisking and cooking until the roux begins to change color.
1 stick unsalted butter, ½ cup all-purpose flour
When the roux has turned a light golden brown, add the trinity: celery, bell pepper, and onion and saute until the vegetables become tender.
1 cup celery, 1 onion, 1 bell pepper
Once the vegetables are tender, add the spice and garlic and saute for about 30 seconds.
1 teaspoon Slap Ya Mama Cajun seasoning, 2 teaspoons Old Bay seafood seasoning, 1 tablespoon garlic
Add the broth a little at a time, stirring to bring all the ingredients together to form a thickened gravy.
4 cups crawfish stock
Stir in the crawfish tail meat, and then the cream and lemon juice.
1 cup heavy cream, 2 pounds Crawfish Tail Meat, 1 tablespoon fresh lemon juice
Simmer on low heat for about 20 minutes.
Serve over hot cooked rice and garnish with parsley.
1 tablespoon fresh parsley, 6 cups parboiled rice
