Sea Bass en Papillote (Ultra-Tender) | IDDSI Level 6 Recipe

IDDSI Level 6 (Soft & Bite-Sized) | 30 minutes | Easy

Sea bass en papillote (紙包鱸魚) adapts the classic French technique of cooking fish sealed in a parchment paper parcel for the Hong Kong care kitchen context — using a Cantonese-inspired ginger, soy and sesame seasoning. The sealed parchment creates a completely enclosed steaming environment where the fish cooks in its own moisture and the aromatics, resulting in an interior so tender and moist that it exceeds the softness achievable by any other dry-heat or pan method. Sea bass (鱸魚) is already one of the most naturally tender white fish available; cooked en papillote it achieves a yielding, moist, perfectly flaking texture throughout, meeting IDDSI Level 6 (Soft & Bite-Sized) comfortably. The sealed packet also makes portioning and serving hygienic and simple.

Ingredients (3–4 servings)

Main:

• 2 sea bass fillets (skin removed), approximately 150g each

Marinade and aromatics (per parcel):

• 4 slices fresh ginger
• 1 spring onion, cut into 5cm lengths
• 1 tablespoon light soy sauce
• 1 teaspoon Shaoxing rice wine
• 1/2 teaspoon sesame oil
• 1/2 teaspoon neutral oil
• Pinch of sugar
• White pepper, a pinch

Equipment:

• Baking parchment or aluminium foil (one large sheet per fillet)

Method

1. Preheat oven to 200°C. (Alternatively, this works in a steamer or wok with a lid using the foil method.)
2. Cut parchment paper into two large rectangles, approximately 35cm × 30cm each.
3. Mix soy sauce, Shaoxing wine, sesame oil, neutral oil, sugar and pepper in a small bowl.
4. Lay each parchment sheet flat. Place ginger slices and spring onion in the centre. Place one fish fillet on top.
5. Spoon the soy mixture evenly over the fish.
6. Fold the parchment over the fish and crimp/fold the edges tightly to create a sealed parcel. Ensure no steam can escape.
7. Place parcels on a baking sheet. Bake at 200°C for 14–16 minutes. (For a steamer: steam on high heat for 12–14 minutes.)
8. Remove from oven. Rest the sealed parcels for 2 minutes — the residual heat continues cooking gently.
9. For IDDSI Level 6 serving: open the parcel carefully (hot steam will escape). Remove all ginger and spring onion garnish. Use a fork to break the fish into approximately 1.5cm flakes along the natural muscle lines. Confirm all skin is absent. Spoon the accumulated parcel juices over the fish pieces as sauce.

Texture Test

Fork pressure test: Passes Level 6 — sea bass cooked en papillote breaks at the natural flake lines of approximately 1.5cm; each flake yields instantly under gentle fork pressure; the flesh is moist, cohesive and uniformly tender throughout — no drier edges or firmer centre.

Moisture check: The parcel juices — a combination of fish moisture and the soy-ginger seasoning — provide excellent coating. This is one of the moistest cooking methods available for fish.

Safety Notes

⚠️ Remove all aromatics before serving — ginger slices and spring onion pieces must be completely removed from the fish before flaking for dysphagia service.

⚠️ Skin check — ensure fillets are completely skin-free before cooking. Fish skin can be difficult to remove cleanly from a cooked fillet; remove it from the raw fillet.

⚠️ Bone check — sea bass fillets from supermarkets are generally pin-bone free; confirm by running fingers along the centre line of the raw fillet.

⚠️ Hot steam — opening the parchment parcel releases hot steam; open away from the resident’s face; allow to cool to appropriate serving temperature before serving.

⚠️ Fish allergy — confirm no fish allergy before serving.

Sourcing Outside Hong Kong

• United Kingdom: Wing Yip (Birmingham, London, Manchester), See Woo (London), Loon Fung (London)
• United States: 99 Ranch Market (West Coast), H Mart (East Coast), local Chinatown grocers
• Canada: T&T Supermarket (national chain), local Asian markets
• Australia: Burlington Supermarket, Tang’s, local Chinese grocers in Chinatown precincts

• Online: Sous Chef (UK/EU), Amazon.com (US), Yami.com (US)

Fresh white fish fillets (tilapia, sea bass, cod): available at most East Asian fishmongers; frozen fillets at H Mart, T&T, and Wing Yip.

If a specific ingredient is unavailable in your region, the recipe notes alternative substitutions in the Ingredients section. For dishes requiring fresh Cantonese-specific ingredients (e.g. preserved century egg, fresh rice noodle rolls), check with your local East Asian grocer before substituting — texture compliance for IDDSI levels may require specific products.

Nutrition

Approximately 185 kcal per serving (about 150g cooked), 30g protein, 6g fat. Sea bass is an excellent lean white fish with high-quality protein, moderate omega-3, B12, phosphorus and selenium. The papillote method preserves all natural juices and water-soluble vitamins — minimal nutrient loss compared to boiling or poaching. Very low sodium — adjust soy sauce quantity for low-sodium diets.

Cultural Note

Fish steamed in a sealed parcel is not a foreign concept in Chinese cooking — lotus leaf wrapping (荷葉包) and taro leaf wrapping are traditional techniques used in Cantonese and Hakka cuisines for precisely the same reason: the sealed environment intensifies flavour and ensures the most tender possible result. The en papillote technique achieves the same outcome using accessible kitchen materials. The ginger-soy flavour profile in the parcel gives this dish a distinctly Cantonese character while using a technique that has recently become popular in Hong Kong home cooking through cooking shows and food media.
