Steamed Cod Fillet with Silken Tofu | IDDSI Level 5 Recipe

IDDSI Level 5 (Minced & Moist) | 25 minutes | Easy

Cod fillet is one of the most naturally suitable fish for IDDSI Level 5 preparation. Its flesh is white, lean and flakes apart along clear muscle lines with minimal fork pressure — each flake falls to 4mm or below without the need for blending or additional processing. Silken tofu is equally well suited: soft enough to crush under gentle tongue pressure, smooth throughout, and free from fibrous or gritty texture. Steaming the two together in a Cantonese-style ginger and light soy glaze allows the tofu to absorb the fish’s natural sweetness, producing a dish that is texturally compliant, nutritionally balanced, and culturally familiar to Hong Kong residents.

Ingredients (2 servings)

Main:

• 200g boneless, skinless cod fillet (fresh or fully thawed frozen)
• 1 pack silken tofu (approximately 300g)
• A few slices of fresh ginger, cut into fine shreds

Sauce:

• 1 tablespoon light soy sauce
• 1 teaspoon sesame oil
• 2 tablespoons water
• 1/4 teaspoon sugar

Optional garnish:

• A small pinch of finely sliced spring onion (for presentation only; omit if strict Level 5 texture compliance is required)

Method

1. Rinse the cod fillet gently under cold water and pat thoroughly dry with kitchen paper. If using frozen fillet, thaw completely and pat very dry to prevent watery steaming liquid.
2. Remove the silken tofu from its packaging with care — it is fragile. Slice into pieces approximately 1.5–2cm thick and arrange flat on a heatproof steaming plate.
3. Lay the cod fillet on top of the tofu slices. Scatter the ginger shreds evenly over the fish.
4. Combine the sauce ingredients and stir until the sugar dissolves. Spoon evenly over the fish and tofu.
5. Bring a wok or steamer to a rolling boil over high heat. Place the steaming plate inside, cover tightly, and steam over high heat for 10–12 minutes (adjust for fillet thickness) until the fish is fully opaque and cooked through.
6. Remove the plate from the steamer. Using a fork, gently separate the fish to confirm it flakes into small pieces of 4mm or less with minimal pressure.
7. Add the optional spring onion garnish immediately before serving if used. For strict texture compliance, omit.

Texture Test

Fork pressure test (Level 5): The cod flesh separates readily along its natural grain lines under light fork pressure into flakes of 4mm or below; the fish cannot be picked up whole on a fork. Silken tofu crushes immediately under gentle fork pressure into a smooth, lump-free mass.

Tongue pressure test: Both the fish and the tofu can be mashed against the palate using tongue pressure alone, with no chewing movement required — meeting the core IDDSI Level 5 (Minced & Moist) criterion.

Safety Notes

⚠️ Bone check is mandatory — cod is generally low in bones but not bone-free. Run your fingers along the entire fillet before and after cooking; remove any pin bones with tweezers before steaming. Check again after cooking before serving.

⚠️ Do not over-steam — cod becomes dry and slightly rubbery if over-steamed, making it harder to break down. 10–12 minutes is sufficient for a fillet of average thickness (2–3cm); thinner fillets may be ready in 8 minutes.

⚠️ Use silken tofu only — firm or extra-firm tofu is too dense for Level 5. Only silken tofu (絹豆腐) or soft tofu (嫩豆腐) meets the texture requirement.

Sourcing in Hong Kong

• Cod fillet: PARKnSHOP and Wellcome frozen sections stock Atlantic and Pacific cod fillets in vacuum-sealed packs; wet market fish stalls carry fresh cod or similar white fish — ask the fishmonger to debone before purchase
• Silken tofu (絹豆腐 / 嫩豆腐): Available at all major supermarkets and wet market tofu stalls; look specifically for silken or Japanese-style tofu for the smoothest texture

Nutrition

Approximately 180 kcal per serving (about 250g), 22g protein, 7g fat. Cod is one of the leanest high-quality protein sources available — approximately 18g protein per 100g — making it exceptionally efficient for elderly residents who need maximum protein from small portion sizes. Silken tofu adds further plant protein, calcium and isoflavones. The combined dish is low in sodium (when made with reduced-sodium soy sauce), low in saturated fat, and rich in complete protein, supporting muscle maintenance and overall nutritional adequacy.

Cultural Note

Cantonese steamed fish (清蒸魚) is among the most revered preparations in Hong Kong cooking, prized for showcasing the natural sweetness and delicacy of fresh fish with minimal seasoning. While cod is not a local species, its fine white flesh responds beautifully to the Cantonese steaming technique and has become a regular feature of Hong Kong family tables. Preparing this dish for residents with dysphagia honours that cultural familiarity — the aroma of ginger and light soy rising from a freshly steamed plate carries deep associations with home cooking and care.
