Preheat Broiler
Mix lemon juice, olive oil, and melted butter in a shallow bowl. Set aside
In another shallow bowl, mix all-purpose flour, spices, lemon zest, salt and pepper.
Gently squeeze liquid from thawed fish and pat fish fillet dry with paper towels.
Dip fish in the lemon butter suace then dredge in the flour mixture. Shake off excess flour.
Heat 2 tbsp olive oil in a cast iron skillet over medium-high heat (the oil should be shimmering). Sear fish on each side to give it some color and create a crisp breading (4 minutes per side).
Add halved tomatoes and capers to the dish and top with thin lemon slices.
To the remaining lemon butter sauce, add the white wine and minced garlic and mix. Drizzle all over the fish fillets and tomatoes in the pan.
Broil in the heated oven for 7-9 minutes until the tomatoes are blistered and the cod flakes easily with a fork.
Remove from heat and sprinkle with chopped parsley.
