This is a delicious way to prepare fish, but make sure you either have a well ventilated kitchen or are cooking outdoors! Trout, snapper and tilapia all work well for this.
To lighten this recipe, remove ALL butter. Sprinkle herbs straight onto fish & heat a few tsp of olive oil in a cast iron skillet. I've found that farm-raised catfish filets are fairly thick, so I cut them in half and cook about 5 min per side. After heating the oil on high & adding the fish, I turn my burner down to med to finish cooking. They still are blackened enough for me, and this helps cut down on the amount of smoke produced. - 17 Sep 2003 (Review from Allrecipes USA and Canada)
Several years ago (and many times since) I had blackened fish at what is considered Milwaukee's finest seafood restaurant, and from that first bite I was smitten. Over the years I've tried it at home with different seasonings and finally found a seasoning blend I loved. Hubby and I also perfected the method--we eliminate the smoke issue by heating the cast iron pan over fiery hot coals and blacken the fish outdoors! Bored with the same seasoning, I wanted to try my hand at mixing one up myself and happened along this recipe. I realized that between the three peppers this might be a little too hot for us, so I cut the cayenne to 1/2 tsp. leaving the amounts of the other peppers the same. It still was too hot for hubby, so next time I'll cut the white and black peppers back a bit too, to maybe 3/4 tsp. each--but this is just a matter of personal taste. I also added some garlic powder. I like using a thinner filet for this method of preparation, and tilapia is a perfect choice. The final result? This is blackened fish perfection, as fine as I had in that first restaurant experience. Love this seasoning! - 08 Feb 2009 (Review from Allrecipes USA and Canada)
I LOVE THIS RECIPE! I use it on Tilapia mostly. I ad 1 tsp of garlic powder to the mixture. I place fish on foil, sprinkle with olive oil & liberally with spice mix on each side, put on a dollop of butter, and wrap each piece in its own package. I cook on the bbq for 10 minutes each side. On rainy days, I bake in the oven at 425` for 10 minutes on each side. Turns out perfect every time. Thanks for sharing. - 27 Oct 2009 (Review from Allrecipes USA and Canada)
