For the fish: Dredge the fish on both sides in the flour. Then, beat the eggs in a bowl using a fork or whisk. Take a saute pan and coat the bottom of the pan with the olive oil, so it is fully covered. Then turn the heat on medium, being careful to not let the oil burn. Splash in a speck of the egg batter to see if the oil is hot enough; the egg will puff up when the oil is ready. At this point, dip the dredged fish into the beaten egg, making sure to cover both sides well, and then place in the saute pan with the hot oil. Let the fish cook on each side until golden brown; be careful not to burn fish in the hot oil. Also, please note that the fish is very tender and breaks easily, so use caution when flipping the fish with a metal spatula or tongs.

For the margarita sauce: In another saute pan, add half of the butter, the chicken stock, the wine, pinch of salt and pepper, and squeeze in three-quarters of the fresh lemon. Make sure to save a few lemon wheels for garnish and set aside. Simmer the sauce for several minutes on medium heat, and then add the cooked fish to the sauce and let that simmer on low heat for a couple of minutes more. This is to infuse the sauce flavor with the egg-battered fish.

For the potatoes: Take the potatoes and cut into cubes. Par-cook them by boiling them in a small pot of water until they begin to soften, but still retain some firmness. In another saute pan over medium-low heat, coat the bottom of the pan with the olive oil and add the butter. Once the butter and olive oil have joined together, add the potatoes to the mixture and turn the heat to medium-high. Next, add the paprika, salt and pepper to taste. Stir the potatoes so that they are all coated evenly with the mixture. Taste one of the potatoes to know when they are finished cooking (they should be slightly crispy on the outside and soft on the inside). Place the cooked potatoes in a bowl and strain any excess oil from the potatoes. Garnish the potatoes with the parsley and finish with a pinch of table salt.

Plate the fish from the margarita sauce, then pour just a bit of the sauce over the fish to highlight the bottom of the plate surrounding the fish. Pour the remaining sauce into a small cup for dipping the fish and/or potatoes. Garnish the top of the fish pieces with 2 thinly sliced lemon wheels and a parsley sprig.
