Salt Crusting — Fish, Poultry, and Whole Vegetables

Ingredients

• 800 g whole branzino (gutted, gills removed, scales intact)
• 1000 g fleur de sel or sea salt, coarse
• 500 ml water
• 2 egg whites
• 1 lemon, halved
• 4 sprigs fresh thyme

Method

1. 1
   Rinse branzino inside and out; pat completely dry with kitchen paper — moisture prevents crust adhesion.
2. 2
   Stuff cavity with lemon halves and thyme sprigs; do not season inside — salt crust will season through osmosis.
3. 3
   Combine salt, water, and egg whites in a bowl; mix with a fork until texture resembles wet sand — this is the binding paste.
4. 4
   Spread 200 g salt paste in a 2 cm layer on a baking tray lined with parchment; place fish on top.
5. 5
   Cover fish entirely with remaining salt paste (at least 1.5 cm thick on all sides); smooth surface with a damp spatula.
6. 6
   Bake at 200°C for 20 minutes; crust should be pale golden and hardened (test with a tap — it will sound hollow).
7. 7
   Cool 3 minutes; strike crust with the back of a spoon to crack; peel away salt layer in large pieces.
8. 8
   Brush remaining salt crystals from skin; fillet at table — flesh will be perfectly seasoned, steamed-poached tender, and moist.
9. 9
   APPLICATIONS: Whole poultry (40 min at 200°C for 1.5 kg bird), celeriac rounds (25 min at 180°C for 500 g piece), whole beetroot (45 min at 200°C for 400 g).
10. 10
    KEY: Moisture escape into salt produces gentle osmotic seasoning and steam cookery — texture is between poached and braised.

    Technique Demonstration | 4 servings
13. 13
    5 kg whole sea bass or branzino — gutted, scaled, cavity cleaned
14. 14
    500 g coarse sea salt (Mediterranean, grain size 2–3 mm)
15. 15
    250 g egg whites (approximately 7–8 eggs)
16. 16
    30 g fresh herbs (rosemary, thyme, bay leaf — or lemon zest)
17. 17
    15 ml water
18. 18
    Whisk egg whites with water until foamy; fold in coarse sea salt and fresh herbs until mixture resembles damp sand.
19. 19
    Spread 5 mm layer of salt mixture on baking tray; nestle whole fish on salt bed, pressing gently so fish sits level.
20. 20
    Cover fish entirely with remaining salt crust, pressing firmly around body, head, and fins; crust should be solid and smooth.
21. 21
    Roast in preheated 200°C (392°F) oven for 25–30 minutes (cooking time = 12–15 minutes per 500 g).
22. 22
    Remove from oven; crack crust with back of knife, then lift away carefully; salt seals in moisture while fish cooks in own steam.
23. 23
    Lift fillets cleanly from backbone; flesh will be moist, delicate, and seasoned evenly throughout.
24. 24
    FOR POULTRY (1.5 kg bird): Increase salt crust to 1 kg; roast 55–65 minutes at 200°C (392°F).
25. 25
    FOR VEGETABLES (beetroot, celeriac, whole onions): 45–60 minutes at 180°C (356°F) depending on size.
26. 26
    PRINCIPLE: Salt crust creates controlled steam environment; eliminates surface drying while maintaining even heat distribution.
27. 27
    For a dramatic tableside presentation, construct the crust in an oval dish rather than on a tray — the dish frames the presentation and makes transport easier
28. 28
    Test the crust for doneness with a metal cake tester or thin probe inserted through the top — the probe should emerge warm (not hot) to the touch for fish, indicating the interior is cooked
29. 29
    For whole beetroot, add star anise and orange zest to the salt crust — the aromatic steam permeates the vegetable significantly over the long roasting time required
30. 30
    For salt-crusted chicken, truss tightly and stuff the cavity with lemon and herbs — the steam from the cavity also flavours the interior
31. 31
    After cracking, present the food at the table in the dish before transferring — the waft of herb-scented steam is part of the experience
