Sorry to say, I don't have the recipe because I just cooked it off the top of my head!
Basically I started out with the roux (dark) added the trinity and fish & veg stock , a touch of fish sauce. Added cajun seasoning and hot sauce to taste. Added: garlic , shrimp , oysters , crawfish tail meat , whole crawfish , scallops , orka , gumbo file and a can of roasted tomato's. Garnished with green onions and cooked rice. I use Zatarain's rice , it has more flavor then plain white rice.
