In a mixing bowl, combine the beaten egg, flour, sazon goya, milk, salt and pepper. Whisk to make a smooth batter.
Prepare the Fish:
Season the fish with salt, pepper and ground cumin. Dip the fish fillets in the batter, letting the excess drip off.
Heat about 2 inches of oil in a skillet. Fry the fish for about 5 to 7 minutes until crispy and brown. Remove the fish and place on paper towels. Season with salt and pepper and serve warm.
