Pla Pao — Salt-Crusted Grilled Fish / ปลาเผา

Central Thai and coastal Thai — the technique is common throughout the coastal provinces and river valleys of Thailand

Pla pao (roasted fish) is the technique of packing a whole fish in coarse salt mixed with kaffir lime leaves or lemongrass, then grilling directly on the charcoal until the salt crust is hard and slightly blackened. The salt crust performs two functions: it insulates the flesh from direct heat (preventing the outside from charring before the inside is cooked) and it seasons the fish through osmotic exchange without making it aggressively salty. When the crust is cracked at the table, the interior is steamed-grilled to perfection — juicy, fragrant from the kaffir lime embedded in the salt, and aromatic from the charcoal smoke. Snakehead fish (pla chon) and grey mullet are the traditional choices; the technique works for any whole fish 400–800g.

Pla pao demonstrates that restraint is a cooking technique — by protecting the fish from direct heat with a salt shell, you get the cleanest expression of the fish's natural flavour with the aromatic contribution of the leaf-infused salt.
