Heat a large fry pan with a medium to medium-high heat and add in the sunflower oil

Meanwhile, pat all the seafood completely dry with paper towels, then cut the cod fillets into bite-sized pieces and the squid into 1/2 inch (1.25 cm) thick rings

Add the flour into a large bowl, season with sea salt and mix together, then coat each seafood item separately in the flour until well coated, shaking off any excess flour

Once the oil is nice and hot, about 10 minutes, add in the pieces of cod, making sure they´re all in a single layer, cook for 3 to 4 minutes or until golden fried all around, then remove from the fry pan, shaking off any excess oil and over a wire rack with paper towels underneath

Let the oil heat for a couple minutes, then add in the squid rings, making sure they´re all in a single layer, fry for 2 to 3 minutes or until golden fried all around, then remove and add over the wire rack

Once again, let the oil heat for a couple of minutes, then add in the shrimp all in a single layer, fry for 1 to 2 minutes or until golden fried, then add over the wire rack

Transfer all the fried seafood into a platter, season with a kiss of sea salt, then garnish with lemon wedges and fresh parsley, serve at once, enjoy!
