Method
- Pat catfish fillets completely dry. Mix paprika, cayenne, garlic powder, oregano, salt, and black pepper; coat both sides of each fillet evenly.
- Heat oil and 1 tbsp butter in a large skillet over high heat until just smoking. Lay in fillets and sear undisturbed 3-4 minutes per side, until a dark crust forms and fish flakes easily (145°F / 63°C). Remove to a plate.
- Lower heat to medium-high. Add corn to the same skillet and let it sit undisturbed 2-3 minutes to char in the leftover fond, stirring occasionally.
- Add garlic and cook 30 seconds until fragrant, then stir in cherry tomatoes and cook 2 minutes until they just begin to soften and release juice, scraping up any browned bits.
- Off heat, swirl in remaining 2 tbsp butter, lime juice, and cilantro. Season with a pinch of salt to taste.
- Spoon the relish over the catfish and serve immediately.

The Why · No Anecdotes
The science, not a story about my childhood.
Why does the spice crust turn black instead of just brown?
Paprika and cayenne contain sugars and proteins that undergo the Maillard reaction rapidly at high heat, and the dense spice coating chars faster than the fish itself because it's a thin layer in direct contact with the hot pan. This creates the classic dark, intensely flavored crust before the interior overcooks.
Why char the corn in the same skillet you just cooked the fish in?
The browned bits (fond) left behind after searing fish are concentrated proteins and caramelized sugars packed with flavor. Adding corn to that same fat picks up those compounds by dissolving them into the vegetable's surface, so the relish tastes like it simmered with the fish instead of being a separate component.
