Caramelised Fish (Cá Kho): Clay Pot Braising

Cá kho tộ — fish braised in a clay pot with caramel, fish sauce, and aromatics — is among Vietnam's most beloved home dishes. The technique produces a lacquered, intensely flavoured fish with a sticky glaze that is simultaneously sweet, savoury, and slightly bitter from the caramel. The clay pot is not incidental — its porous walls absorb heat and distribute it evenly, preventing the delicate fish from overcooking at the contact points.

Fish (catfish, salmon, or other firm-fleshed variety) braised in a clay pot or heavy-bottomed pan with Vietnamese caramel sauce, fish sauce, sugar, ginger, and chilli over very low heat until the liquid reduces to a sticky, coating glaze. The technique is a low-heat, long, patient reduction.

Cá kho is eaten with plain white rice — the rice is essential as a vehicle for the intensely flavoured glaze. The dish is too intense to eat alone; the rice absorbs and mellows. The balance is the fish's richness, the caramel's depth, the fish sauce's umami, and the rice's neutrality.
