Heat a pan on medium heat.
Dip the thawed fillet into the melted butter completely covering it and coat with the mix of spices.
Add 2 tbs butter to hot pan and add fish.
2 minutes on each side.
Now I have to warn you. There is A LOT of smoke. You are essentially burning the spices and searing the fish. So please, open some windows and put a fan facing out. I now know why most of the recipes for anything blackened involved a grill and the great outdoors.
This is so good but it does have a kick to it. If you are looking for something not to mouth-numbing omit the red pepper flakes.
Need MORE of a kick? Add Cayenne Pepper.
Have a Ice Cold Milk at the ready & good luck.
