salt - enough to cover fillets (for drawing out moisture)
oil - 1-2 tablespoons (for frying, use a neutral oil)
butter - about 1 tablespoon (a knob for basting)
lemon - 1/2 lemon (for squeezing on the plate, avoid skin contact)
Instructions
Draw out moisture: Lay the sea bass fillets skin-side down on salt and leave for 15 minutes to draw out moisture.
Rinse and dry: Rinse off the salt from the fillets and pat them dry thoroughly.
Initial pan heat: Heat a pan without oil. Place the fillets skin-side down and press gently for a few seconds.
Rest to relax membrane: Once the skin shows a light color, remove the fillets from heat and let them rest briefly to allow the outer membrane to relax.
Add oil and press: Add a little oil to the pan and return the fillets skin-side down. Place a light weight, such as a grill press, on top and leave for a few minutes.
Add butter and baste: Add a knob of butter to the pan and baste the fish briefly.
Flip briefly and remove: Flip the fillets briefly just to warm the flesh without overcooking, then remove from heat.
Serve with lemon: Squeeze lemon juice on the plate, avoiding contact with the crispy skin, and serve immediately.
