Step 2. Caramelize and Cook the Catfish

  • In a pot over medium heat, add 2 tablespoons of sugar and stir constantly until it melts into a beautiful amber brown color. Be careful not to burn it!
  • Add the marinated catfish to the caramel, ensuring each piece is coated. Gently turn to avoid breaking.
