Instructions

The salt crust acts as an insulated oven inside your oven — the fish steams in its own juices and emerges incredibly moist. This is the probe-based, water-only version. No egg whites, no timer guessing.

--- Prep ---
1. Preheat oven to 200°C.
2. Make sure the fish is gutted and scaled. Pat it dry inside and out.
3. Stuff the cavity with the lemon slices, crushed garlic, thyme, and rosemary.

--- Build the crust ---
4. In a large bowl, combine 2 kg coarse salt with cold water a splash at a time, mixing until you reach a "wet snow" or "packable wet sand" consistency. Squeeze a handful — it should hold its shape when squeezed. Falls apart = more water (1 tbsp at a time). Soupy = more salt.
5. On an oven tray, spread one third of the salt mixture in a layer slightly longer and wider than the fish. This base prevents the metal tray from conducting heat directly into the bottom of the fish (which would overcook the underside).
6. Place the fish on top of the salt bed.
7. Insert your temperature probe into the thickest part of the fish, just behind the head, over the spine. The probe lead should exit cleanly out one end.
8. Cover the fish completely with the remaining salt, packing it firmly with your hands like you're sculpting. NO air pockets, NO thin spots. Pile a little extra around where the probe enters — that's the one place a brittle water-only crust might split.

--- Bake ---
9. Bake at 200°C until the probe reads 130°F (54°C) at the thickest part of the fish. For a ~1.3 kg fish this is typically 20-25 minutes, but trust the probe, not the clock.
10. If a crack appears mid-bake, pull the tray, slap on a wet-salt patch, and return to the oven. Cracks vent steam and ruin even cooking.

--- Rest (this is the make-or-break step) ---
11. Pull the fish at 130°F internal. Let it sit in its UNBROKEN crust for exactly 5 minutes on the counter (8 minutes maximum). Residual heat trapped inside the salt dome will push the internal temperature up to a perfect 140-145°F. Do NOT exceed 8 minutes — the insulation will keep cooking the fish toward dry and chalky.

--- Serve ---
12. At the table, crack the crust with the back of a heavy spoon. Tap around the edges first to break the seal, then gently lift the top off in pieces.
13. Brush all loose salt away.
14. Make a shallow incision along the skin and peel it back — it lifts off easily.
15. Remove the dorsal fin. Cut along the central spine and gently lift the top fillet off the bones in one piece.
16. Flip the fish and repeat for the second fillet.
17. Drizzle with good olive oil and serve. Boiled potatoes and blanched vegetables pair beautifully. Avoid strong sides — they'll overpower the delicate fish.

Personal Notes

WHY THIS RECIPE DIFFERS FROM THE VIDEO

The source video uses egg whites as a binder and a 25-minute time-based bake. This version uses water only and a temperature probe. Same technique, just modernized.

--- The water vs. egg-white question ---
Egg whites form a rigid ceramic shell when baked, which makes the crust stronger and more dramatic to crack open. Water-only crusts are held together by mechanical interlock of coarse salt grains — slightly more brittle, but the fish inside tastes identical. Water version is 2-minute prep vs 10+ minutes for egg whites, and you don't get egg on your hands. Both work.

--- Why coarse salt only ---
Fine salt + water makes a paste that won't pack. Coarse salt grains interlock mechanically and dissolve slowly enough not to over-salt the fish. Sea salt, kosher (Diamond or Morton), or rock salt all work.

--- Why probe-based over time-based ---
Time-based recipes are someone else's guess for someone else's fish in someone else's oven. The probe makes them obsolete. Insert into the thickest part of the fish (over the spine, behind the head) before sealing the crust. The salt-water mixture seals tightly around the probe shaft as it bakes — the puncture is functionally negligible.

--- The carryover and rest-time math ---
The salt crust is an excellent insulator. After you pull the fish, internal temperature continues to rise 10-15°F during the 5-minute rest. Pulling at 130°F gets you to a perfectly cooked 140-145°F final. The 5-8 minute rest window is critical — too short and it's underdone, too long and the dome's residual heat dries the fish out. Crack the crust on time.

--- Doneness alternatives ---
For a more modern, silky 'just-set' texture, pull at 122°F and rest 5 minutes for a ~132°F final. For traditional fully-flaky doneness (this recipe's default), pull at 130°F.

--- If something goes wrong ---
Crust cracks mid-bake: patch with wet-salt and continue.
Fish reads done very fast: trust the probe, don't extend cook time.
Forgot to stuff cavity: just bake it plain, still excellent.

Family verdict (2026-05-19, ⭐4/5): taste was excellent — fish came out tender and glorious. BUT the experience is a hard no for repeats: enormous kitchen mess (2kg of crusted salt to dispose of), the fishy/salty waste has to leave the house immediately or it stinks, and serving (cracking the dome, plating off bones at the table) was fiddly and stressful. Flagged as a once-in-a-lifetime / dinner-party-only dish, not weeknight. DKG: "glad we did it twice — the first and the last." Save this for a special occasion when the kitchen drama is part of the show, not a weeknight.
