A whole fish steamed with ginger and spring onion, then finished at the table with a pour of hot soy sauce followed by smoking-hot oil — the oil and soy combining on the fish's surface in a aromatic sizzle that serves as both flavour addition and aromatic spectacle. Qing zheng yu is the most fundamental Cantonese preparation and the clearest demonstration of the Cantonese principle of ingredient quality as primary preparation: a correctly steamed whole fresh fish needs nothing beyond the soy sauce and a few aromatics to be exceptional.
**The fish:** Fresh whole fish — sea bass, snapper, grouper, or any firm white-fleshed fish with a clean, sweet flavour. Scored (Entry TH-76 principle). The freshness of the fish is the entire preparation — a fish steamed hours after death cannot produce the same result as one steamed within hours of purchase. **The steaming:** - Line the steaming dish with ginger slices and spring onion sections (these go under the fish, perfuming the steam that rises around it). - Place the fish on top. - Place additional ginger julienne and spring onion on top of the fish. - Steam over vigorous water for 8–12 minutes depending on size. Test with a skewer at the thickest point (Entry TH-76 principle — the trembling, not boiling, steam caveat does not apply here: Cantonese steamed fish uses vigorous steam). **The finishing:** 1. Remove the fish from the steamer. Discard the steaming liquid and aromatics. 2. Arrange fresh ginger julienne and spring onion threads on top of the fish. 3. Pour 2 tablespoons of light soy sauce mixed with a small amount of sugar along the length of the fish. 4. Heat 3–4 tablespoons of neutral oil in a small pan until smoking (220°C). 5. Pour the smoking oil over the spring onion and ginger — it sizzles and chars the top of the aromatics slightly, releasing their full flavour into the fish. Decisive moment: The freshness of the fish and the temperature of the finishing oil — both non-negotiable. A stale fish produces a preparation with off-flavours that the soy sauce and ginger cannot correct. The finishing oil below 200°C produces a quiet sizzle rather than the dramatic aromatic release that is the preparation's signature.
