I brought the convo here because there isn't enough "culinary" in here.
It doesnt matter if you use "shrimp" seasoning on fish or chicken or beef or vegetables etc. What does matter is that you use Chef Paul Prudhomme's Redfish Magic if you want to authentically Blacken any of those, or anything else. My opinion on the matter is based on extensive knowledge and experience from trial and error. I discussed this same thing with Kev before.
Blackening is a Cajun technique but there is a big difference in Cajun seasoned fish and blackened fish. Your fish was not blackened. Nothing wrong with what you did at all, its good that way too.
Just FYI, Chef Prudhomme is credited for creating the blackening technique. He used butter instead of olive oil, after you get the hang of it you should try it with butter and see if you like it better. Butter is not as forgiving as oil. I gotta lot of respect for Prudhomme, he was as hard a working chef as there ever was. He was the first American Head Chef at the Commanders Palace in NO and made Emeril the Head Chef when he left to run his own place. The French (culinary world) think highly of him.
