Open a window and turn on a fan. It’s about to get smoky.
In a shallow bowl, combine the thyme, garlic powder, paprika, sugar, black pepper, cayenne, and salt.
In a large skillet, preferably cast iron, over medium0high heat, melt the butter. Dredge each fillet in the spice mixture on both sides, lay the fillets skin side down in the hot pan, and cook for 4 minutes. Be patient and let it go until literally “blackened”. Flip the fish and cook until just cooked through, probably just 1 minutes. Serve at once.
