In a deep skillet or dutch oven mix the butter and flour together over low heat to form a roux (a thick, smooth, bubbly mixture).
Add the onions, celery and garlic and saute until tender.
Add the tomatoes, salt, pepper, cayenne and water.
Simmer covered for 20-30 minutes.
Add fillets and cook until tender and flaky, 15-20 minutes.
Serve on a bed of rice.
The amount of cayenne here is set for a mildly hot taste.
It can be increased up to a full teaspoon for the full nuclear version!
