Cut the fresh or thawed fish into pieces and place into a large zip-top bag. Squeeze the lime into the bag with the fish, seal the bag, shake gently and set aside to marinate.
Heat enough oil in a large skillet to cover the entire skillet bottom. While that is coming to high heat (400ºF), prepare a bowl for dredging with the gfJules Flour, salt, and pepper(s) whisked together well.
Using a fork, remove fish pieces, one at a time, and dredge each through the flour mixture, coating each side well, then lay gently in the heated oil.
Cook on both sides until light brown and crispy -- approximately 3-5 minutes per side, depending on the size of the fish. Cut into a piece of fish to be sure it's cooked through (the fish should be white and opaque, not pink or translucent).
Remove and drain on a paper plate or paper towels. Keep warm by placing on a baking sheet in a 175° F oven while finishing remaining fish.
Prepare flour tortillas or wrap cooled tortillas in a towel and microwave for 20-30 seconds, until soft and warm. Add the fish and selected toppings, wrap and enjoy!
