1: Zest 1 lemon and squeeze out its juice. Crush 1 garlic clove with the blade of a flat-bed knife. Prepare and finely chop 1 shallot. Set aside.
2: Prepare 4 seas bass fillet, carefully remove all bones, pat dry and salt the flesh side. Heat the plates.
3: In a frying pan over medium heat, pour 4 tablespoons olive oil and, when hot, place the sea bass fillets skin-side down. Cook for 2 or 3 minutes...
4: ...until the skin side is nicely grilled, check by lifting the fillet. Turn the fillets over.
5: If you don't like the skin (like me), remove it, but it's not essential.
6: Salt the fillets, sprinkle with oregano and cook for 2 minutes.
7: Turn them over again, the top should be nicely toasted, and sprinkle this side with dried oregano.
8: Add to the pan, next to the fillets, 3 tablespoons olive oil, 1 knob butter, the garlic clove and shallot, lemon zest and juice, a little salt and pepper.
9: With the pan slightly tilted, scoop out the cooking juices with a tablespoon and pour them over the fillets. Do this several times to ensure that the fillets are well basted and "nourished".
10: Serve on a warm plate, pouring a little of the cooking juices over each fillet, and adding a dash of lemon juice if desired.
