Louisville secret. Green River style fried fish is cornmeal-breaded, spicy with cracked pepper. Green River is south of Louisville in the Mammoth Cave area, but the recipe apparently originated in Louisville at the Suburban Social Club Fish Fry (Masons) south of Churchill Downs. An occasional Louisville restaurant serves it as cod or scrod, but catfish sounds good.

What year were the pics taken? Prices are way higher now.
Photo undated. I am sure they are higher. Was not meant as an ad so much as a unique local food.
