Instructions

1. 1
   Mix the slurry

   In a small bowl, stir the cornstarch with 30 ml (2 tbsp) water until completely smooth and lump-free. Set it aside near the stove because it will need a quick stir again before using.

   1 minute Room temperature

   Cues: The mixture should look milky and pourable, with no dry starch at the bottom.

   Tip: Cornstarch settles quickly, so stir again just before adding it to the pan.
2. 2
   Build the aromatic base

   Heat the oil in a small pan or wok over medium heat. Add the garlic, ginger, green chilli, and spring onion whites. Stir constantly so the garlic softens and turns pale golden at the edges without browning deeply.

   2 to 3 minutes Medium heat

   Cues: The mixture should smell sharp and savory, and the garlic should look glossy with light golden flecks.

   Tip: If the garlic darkens too fast, lower the heat briefly; burnt garlic will make the sauce bitter.
3. 3
   Add the sauce seasonings

   Pour in the soy sauce, dark soy sauce, red chilli sauce, ketchup, rice vinegar, white pepper, and sugar. Stir for 20 to 30 seconds to combine and lightly cook off the raw edge of the sauces.

   30 seconds Medium heat

   Cues: The mixture will smell balanced rather than harsh, and the color will turn a deep reddish brown.

   Tip: Keep the pan moving at this stage so the sugars in the ketchup do not catch on the bottom.
4. 4
   Loosen with stock

   Add the vegetable stock or water and bring the mixture to a gentle simmer, stirring well to dissolve everything into an even sauce base.

   2 minutes Medium to medium-high heat

   Cues: Small bubbles should break at the surface, and the liquid should look unified rather than separated.

   Tip: For a stronger restaurant-style flavor, use light vegetable stock instead of plain water.
5. 5
   Thicken the sauce

   Stir the cornstarch slurry again, then pour it into the simmering sauce in a thin stream while stirring continuously. Cook until the sauce thickens enough to lightly coat the back of a spoon.

   1 to 2 minutes Medium heat

   Cues: The sauce will become glossy, slightly translucent, and leave a clean line when you run a finger across the back of a coated spoon.

   Tip: If it gets too thick, loosen it with 15 to 30 ml (1 to 2 tbsp) water.
6. 6
   Finish and balance

   Turn off the heat and stir in the spring onion greens and sesame oil, if using. Taste and adjust with a few drops of soy for saltiness, vinegar for extra tang, or a spoon of water if you want a lighter consistency for noodles.

   1 minute Off heat

   Cues: The finished sauce should be glossy, spoonable, and smell garlicky, peppery, and lightly smoky from the sauces.

   Tip: For use as a stir-fry sauce, keep it slightly looser because it will reduce further when tossed with vegetables or noodles.
