Ingredients (Serves 4-6)
Main:
1 local premium frozen Blue-Spotted Grouper
 
Aromatics:
Old ginger: 1 large piece (~80g), sliced & julienned
Spring onions: 6-8 stalks, sectioned & julienned
Fresh coriander: 3 sprigs
Dried tangerine peel (chenpi): ¼ piece, pre-soaked
Jinhua ham: 20g, julienned (optional)
Red dates: 2-3, pitted & julienned
 
Seasonings:
Premium light soy sauce: 4 tbsp
Huadiao wine: 2 tbsp
Cane sugar: 1½ tsp
Cooking oil: 4 tbsp (+ 1 tsp sesame oil optional)
White pepper: to taste
Chicken stock or water: 50ml
 

Method
Step 1: Thawing & Prep
1. Thaw fish in packaging submerged in room-temperature water until fully defrosted.
2. Rinse thoroughly under cold water; clean gills carefully. Trim all fins with kitchen scissors.
3. Gently scrape skin mucus with knife back; rub skin with coarse salt 30 seconds, then rinse.
4. Score both sides diagonally at 45° to the bone, 2cm apart. Lightly score inside belly.
5. Coat fish with 1 tbsp Huadiao wine, white pepper, and ginger slices. Stuff cavity with crushed spring onion sections; rest 15 minutes.
 
Step 2: Aromatics Prep
1. Scrape white pith from softened chenpi; julienne finely.
2. Julienne Jinhua ham; toss with a splash of Huadiao wine.
3. Slice half the ginger thick; julienne the rest. Divide spring onions: crush whites, julienne greens, reserve tips for garnish.
4. Mix julienned ginger, chenpi, ham, red dates, and some spring onion strips to create "Five-Flavor Julienne."
 
Step 3: Steaming
1. Place bamboo chopsticks on steaming plate; layer with ginger slices and crushed spring onion whites to elevate fish.
2. Fill steamer with water; add ginger slices and spring onion sections. Bring to vigorous boil.
3. Place fish on steamer; cover immediately. Steam on high heat: ~8-9 minutes per 500g fish weight.
4. After two-thirds of cooking time, reduce to medium heat to prevent skin splitting.
5. Test doneness: insert chopstick near gill—if it penetrates to bone easily with no blood, fish is ready. Eyes should protrude and turn white.
 
Step 4: Finishing
1. Remove fish; strain accumulated juices, reserve 3 tbsp, discard rest.
2. Arrange "Five-Flavor Julienne" and fresh coriander over fish.
3. Heat cooking oil (+ sesame oil if using) until fine ripples appear (~180°C).
4. Pour evenly over aromatics to release fragrance.
5. In same small pan, combine soy sauce, sugar, reserved fish juices, and stock. Simmer gently until slightly thickened. Stir in remaining 1 tbsp Huadiao wine just before removing from heat.
6. Pour warm sauce slowly along plate edge, avoiding direct contact with fish.
 
Chef's Tips
1. Thawing: Blue-Spotted Grouper has firmer flesh; allow slightly longer thawing time, but never use hot water.
2. Chenpi is key: Dried tangerine peel balances fish oil richness and elevates aromatic complexity.
3. Heat control: Use "high-then-medium" heat to ensure even cooking without overcooking edges.
4. Sauce balance: Fish flavor is concentrated; sauce can be richer, but calibrate sugar carefully to balance saltiness.
