Method
Make Southern Cornmeal Crusted Catfish: Stir together buttermilk or yogurt and hot sauce; brush on catfish and allow to marinate for 10 minutes.
Coat catfish lightly with cornmeal and sprinkle with salt and pepper to taste. Melt butter and olive oil in a nonstick skillet over medium high heat.
When skillet is hot, sauté catfish about 3 minutes on each side, turning only once, until golden and crisp. Serve with relish.
