Steamed coral trout — Cantonese style, with ginger, spring onion and coriander, finished with sizzling oil — is one of the great Asian fish preparations. The gentle steam keeps the firm white flesh moist and delicate; the soy-sherry-stock sauce adds umami depth; the hot oil at the end blooms the aromatics into a fragrance that fills the whole campsite.

Restaurant-grade fish from a camp setup. Works on coral trout, pearl perch, snapper, flathead, barramundi — any firm white-fleshed fish.

• 750g whole coral trout, cleaned + gutted (head on)
• ½ tsp salt
• 4 spring onions, trimmed
• 4 thin slices fresh ginger, unpeeled (3-4cm coin slices)
• 2 tbsp light soy sauce
• 2 tbsp dry sherry (or Shaoxing wine)
• ½ tsp sugar
• 85ml fish stock (or chicken stock)
• 2 tbsp peanut oil (or vegetable oil)
• 1 garlic clove, halved lengthways
• 65g fresh coriander leaves
• Optional: 1 long red chilli, sliced

To serve: steamed jasmine rice, steamed Asian greens (bok choy, gai lan), extra soy sauce on the side.

1. Prep the fish. Pat the fish dry inside + out. Score 2-3 shallow diagonal slashes on each side at the thickest point (helps even cooking + lets the marinade penetrate). Sprinkle salt evenly all over including the cavity.

2. Prep the spring onions. Cut a 5cm piece from each spring onion at the bulb-end — set aside (you'll lay these under the fish). Cut the green tops lengthways into very fine long julienne strips, then chop again into 5cm batons. Keep these reserved for garnish.

3. Set up the steaming dish. Take a heat-proof dish that fits inside your steamer with 2-3cm of clearance. Lay the spring onion bulbs on the bottom of the dish (these elevate the fish + flavour the steaming juices). Place the fish on top.

4. Top with ginger. Lay the ginger slices over the fish — both inside the cavity + along the top.

5. Make the marinade. Combine the soy sauce, sherry, sugar and stock in a small bowl. Spoon evenly over the fish. Marinate 20 minutes, basting once or twice.

6. Steam. Bring a large pot or wok of water to a rolling boil. Place the dish in the steamer (line the steamer with foil or baking paper to catch any drips). Cover tightly. Steam over HIGH heat for 15-20 minutes — until the fish is just barely opaque at its thickest point.

7. Test for doneness. Pierce the fish along the back at the thickest part with a knife — gently lift the blade. Flesh should be opaque white but still moist + lifting in flakes. NOT chalky or dry.

8. Heat the oil. Just before serving, heat the peanut oil + garlic in a small pan or wok until VERY HOT (almost smoking). When the garlic begins to colour, fish it out with a slotted spoon (it's done its job — keep the oil aromatic).

9. Garnish + sizzle. Lift the steamed fish carefully onto a serving plate. Scatter the reserved coriander leaves + the julienned spring onion on top of the fish. Pour the hot oil OVER the herbs (it'll sizzle dramatically + bloom the aromatics).

10. Serve immediately with steamed rice + steamed Asian greens.

• Fish freshness is everything. A fish steamed within 24 hours of catch is in a different league to anything frozen. If using frozen, defrost slowly in the fridge overnight
• Coral trout is iconic on the GBR but expensive. Substitutes that work brilliantly: pearl perch, snapper, jewfish (small one), barramundi, even large flathead
• Don't over-steam. The line between perfect + over is tight (~1-2 minutes). Better to pull early + check; if underdone, return for 2 more minutes
• The hot oil step is the secret. Don't skip it — the sizzle releases the volatile aromatics from coriander + spring onion. Restaurant-quality fragrance
• Camp version — use a large stockpot with a wire rack inside (the cake-cooling-rack trick). Cover with foil if no lid fits. Steam time same
• Sizzling oil with chilli for spice — heat oil with sliced red chilli + garlic; pour both onto the fish
• Vegetarian-adjacent variation: tofu blocks instead of fish — same recipe, 8-10 minutes steaming
• Add Asian flavours: a tablespoon of sesame oil + a pinch of white pepper added to the marinade gives extra depth

One of the great fish preparations in any cuisine, and surprisingly easy at a campsite. The Cantonese method respects the fish — gentle steam, restrained sauce, fragrant aromatics finished with hot oil. The result tastes elegant, refined, restaurant-grade.

If you've caught a beautiful fish on a tropical reef trip — coral trout, snapper, pearl perch — this is the cooking method that does it justice. Crusty grilled is one approach; this is the other. Worth learning both.
