Heat Cast Iron on medium-low before cooking.
Grab 3 bowls. Put half cup of Flour, Salt, and Pepper into the first bowl and mix well. Whisk eggs and milk together in the second bowl, and in the third bowl put the rest of the flour, Garlic Powder, and Paprika.
Crush Crackers into small pieces (you can use a food processor or a sandwich bag). Place in the third bowl and mix well.
Take fish and fillet any bones out if needed. Also, cut into the size you prefer.
Set all 3 bowls in order (1,2,3) by the Cast Iron, with 3 being next to the Cast Iron. This way when the fish is dunked into the third bowl it can go directly into the cast iron.
Place the lard in the cast iron. Once it becomes a liquid, you can start to fry the fish.
Take a piece of fish and roll it in the first bowl fully coating it. Next, place it in the second bowl with the eggs and fully coat as well. After that, coat the fish again fully in the third bowl. Once it's fully coated, lay the fish in the cast iron.
Fry on each side for 4-6 minutes each. Make sure you keep the temp on a medium to prevent from burning. To tell if the fish is done, you should be able to cut into the fish smoothly with a fork. Inside will be white as well.
Continue to do this for the rest of the fish.
Once fish is all cooked, spritz with a lemon and dunk with Tartar sauce. Enjoy!
