1. Dry & Season
Pat the fluke completely dry with paper towels.
Season both sides generously with salt and black pepper.
Dry fish = good sear. This is critical.
2. Heat the Pan
Heat a heavy skillet (cast iron or stainless) over medium-high heat.
Add neutral oil and heat until it shimmers.
3. Sear
Lay the fluke in the pan presentation-side down first:
Press gently with a fish spatula for the first 10–15 seconds to prevent curling.
Cook 3–4 minutes, untouched, until the edges turn opaque and the bottom is golden.
4. Butter Baste
Flip gently.
Add butter, garlic, and herbs to the pan.
Tilt the pan and spoon the foaming butter over the fish for 1–2 minutes, until just cooked through.
5. Rest & Finish
Transfer to a plate and rest 1 minute.
Finish with lemon and a final pinch of flaky salt.
