Ingredients:
- 1 large bunch Gai Lan (Chinese Broccoli), approx. 500g / 1 lb
- 2 litres / 8 cups Water (for blanching)
- 1 Tbsp (15g) Coarse Sea Salt
- 1 tsp (5ml) Neutral Cooking Oil (e.g., groundnut or rapeseed oil)
- 1 large bowl Ice Water (for the shock bath)
- 4 Tbsp (60 ml) Oyster Sauce
- 1 Tbsp (15 ml) Light Soy Sauce
- 2 tsp (10g) Granulated White Sugar
- 4 Tbsp (60 ml) Chicken Stock or Water
- 1 tsp (5g) Fresh Ginger, finely grated (optional, for aroma)
- 1 tsp (5 ml) Sesame Oil (for finishing)
- 1 tsp (5g) Cornstarch
- 2 tsp (10 ml) Cold Water
Instructions:
- Trim the Gai Lan: Cut off and discard the very tough, woody bottom ends (usually about 2-3 cm). If the stalks are very thick, slice them lengthwise down the middle to ensure even cooking. Wash thoroughly.
- Set up the Bath: Fill a large bowl with ice and water and set it immediately next to the stovetop.
- Boil the Water: Bring 2 litres of water to a rolling boil in the large stock pot. Add the coarse sea salt and the neutral oil (this helps keep the greens glossy).
- Blanch the Gai Lan: Submerge the Gai Lan fully into the boiling water. If you have a large quantity, blanch in two batches to keep the water temperature high.
- Cook to Crisp-Tender: Cook for 60 to 90 seconds. The colour should turn vividly bright green. The stalks should still offer slight resistance when pierced.
- Shock Immediately: Transfer the Gai Lan immediately from the boiling water straight into the prepared ice bath. This stops the cooking process and locks in that beautiful colour. Leave for 30 seconds.
- Drain and Plate: Remove the Gai Lan, shake off excess water, and pat briefly with a clean towel. Arrange neatly on a serving platter, ensuring the stalks are laid out uniformly.
- Combine Sauce Ingredients: In the small saucepan, whisk together the oyster sauce, soy sauce, sugar, chicken stock/water, and grated ginger (if using).
- Simmer the Sauce: Bring the mixture to a gentle simmer over medium heat, stirring until the sugar is fully dissolved. Reduce heat to low.
- Thicken the Sauce: In a separate small dish, whisk the cornstarch and cold water to create a smooth slurry. Pour the slurry into the simmering sauce, stirring constantly.
- Achieve Gloss: Cook for 30 seconds until the sauce thickens and becomes glossy, coating the back of a spoon. Remove immediately from the heat.
- Finish the Dressing: Stir in the sesame oil.
- Serve: Drizzle the hot, glossy dressing generously over the arranged Gai Lan just before serving.
