1. Place fish in a shallow dish. Squeeze juice of 1 lime over fillets.
2. Combine chili powder and next 3 ingredients. Sprinkle 1 1/2 Tbsp. seasoning mixture evenly over fish, coating both sides of fillets. Reserve remaining seasoning mixture.
3. Combine cornmeal and reserved seasoning mixture in a shallow dish. Dredge fish fillets in cornmeal mixture, shaking off excess.
4. Pour oil to a depth of 1 1/2 inches in a Dutch oven; heat to 350°. Fry fillets, in batches, 2 to 3 minutes or until golden brown. Drain fillets on wire racks over paper towels.
5. Break each fillet into chunks, using a fork. Place fish in warmed tortillas, and serve with Mango Salsa, Guacamole, and desired toppings. Garnish, if desired.
Cook's Notes: While we love the fried fish flavor, we also tried baking and grilling the flounder fillets. Both are great options. Here's how to do it:
Baked Flounder Fillets: Omit oil from Spicy Fish Tacos recipe. Assemble as directed. Spray cornmeal-coated fish with vegetable cooking spray. Bake at 350° on a lightly greased rack on a baking sheet 12 minutes or until fish flakes with a fork.
Grilled Flounder Fillets: Omit oil and cornmeal from Spicy Fish Tacos recipe. Assemble as directed. Reduce salt to 1 tsp. Sprinkle fish evenly with chili powder, salt, cumin, and red pepper. Lightly grease a large piece of heavy-duty aluminum foil; line cooking grate with foil. Place fish on lightly greased side of foil; grill, covered with grill lid, over high heat (400° to 500°) 8 minutes or until fish flakes with a fork, turning once.
In Mexico, practically every meal is accompanied by a stack of fresh warm corn tortillas, much in the way that bread is served here in America. As you eat, you can wrap whatever is on your plate in a fresh tortilla, and voilá, you have a taco. Almost everything tastes good in a taco smothered with fresh salsa, and that goes for fish as well. Preparing a taco is much like preparing a sandwich; it's all in the assembly. For these fish tacos you will be preparing and then assemblying the fish, the tortillas, the salsa, and the cabbage or lettuce.
Fish Tacos Recipe
* 1 lb of very fresh fish fillets - (Good fish for tacos are firm fish like swordfish or shark)
* Salt and pepper
* Olive oil
* 1 doz corn tortillas (3 tortillas per person)
* Vegetable oil or butter (optional, depending on how you heat your tortillas)
* Cabbage (or iceberg lettuce)
* Cider vinegar
1 Prepare the salsa. Either use store bought or make your own. (See above link for Mango Salsa, which is especially good with fish.)
2 Prepare the cabbage and avocado. Thinly slice cabbage. Put in a small serving bowl. Sprinkle with cider vinegar (about a Tbsp) and salt (about a tsp). Mix in the vinegar and salt. Peel avocado and remove seed. Chop and reserve for later.
3 Heat the tortillas. Unless you have made fresh tortillas from scratch, you will need to soften them somehow. One way to easily soften and heat a tortilla to simply heat it in the microwave for 20-25 seconds on high heat, on top of a napkin or paper towel to absorb the moisture that is released. We often will heat two tortillas at once in the microwave, heating them for a total of 40 seconds.
Another way is to heat a well seasoned (black) large cast iron skillet to medium heat. Add a teaspoon of oil to the pan or spread a half a teaspoon of butter on one side of one tortilla. Place tortilla in the pan (butter side down if you are using butter). As the tortilla sizzles, flip the tortilla with a spatula so that the other side gets some of the oil or butter from the pan. Continue to flip every 10-30 seconds until the tortillas begins to develop air pockets, about a minute. If the pan begins to smoke, lower the temperature. You can skip the butter or oil if you wish and just heat the tortillas up on the skillet without them. We have found that the flavor of packaged tortillas benefits from heating them with a bit of oil.
Remove the tortilla from the pan and place it folded on a plate. If the pan is large enough you can prepare two or more tortillas at once. Continue until all the tortillas (estimate 3 per person) are cooked. Set aside.
4 Cook the fish. Soak the fish fillets in cold water for at least one minute. Pat dry with a paper towel. Heat a large stick-free skillet to medium high heat. Add a couple of teaspoons of olive oil to the skillet. Place fish on skillet. Cooking time depends on the thickness of the fillets. A thin fillet may take only one minute on each side to cook. A thicker fillet may take a couple of minutes. Fish should be still barely translucent when cooked. Break off a piece and test if you are not sure. Do not overcook the fish. Remove from pan when done to a separate plate. Sprinkle with salt and pepper.
5 Assembly. I think tacos are best when you assemble them yourself. Place the plate of tortillas, the plate of fish, the salsa, the cabbage, and the avocados on the table and let everyone assemble their own.
