Cold sauces & condiments
Soy Sauce Supreme Base (Si Yao Wong)
豉油皇 · A foundational Cantonese seasoning base — literally 'King/Kingdom of Soy Sauces' (豉油皇) — built on dark soy, light soy, and water with sugar and optional aromatics. Functions as a reusable condiment component for dipping, drizzling, stir-frying, and braising; it is a base, not a finished dish.
The formula
4:1:16 dark soy : light soy : water, +sugar to taste
Dark soy dominates for color and gloss; light soy supplies primary salinity; water balances intensity. Source 2 (Star Kitchen) exact: 2 tbsp dark + 1/2 tbsp light + 1/2 cup (8 tbsp) water + 1 tsp sugar. Master-stock versions (Sources 3 & 4) use a lower water:soy ratio of roughly 3–4:1 for braising.
Identity
- Foundational Cantonese seasoning base, not a finished dish
- Reusable component — bottled and drawn from across multiple applications
- Dark soy–led formula producing mahogany color and glossy finish
- Dual role: light condiments (dip/drizzle) AND heavy applications (master-stock braise)
- Literal meaning 'King/Kingdom of Soy Sauce' reflecting its prized status in Cantonese kitchens
Ingredients
| Base | dark soy sauce (老抽) | Provides mahogany color, mild sweetness, and glossy finish — the dominant ingredient |
| Base | light soy sauce (生抽) | Supplies primary salt and savory flavor; used in smaller proportion than dark |
| Liquid | warm water (or reserved shiitake soaking liquid) | Dilutes and balances; mushroom water (Source 1) adds free-glutamate umami |
| Sweetener | sugar (or rock sugar) | Rounds the salinity and balances the salty backbone; must fully dissolve |
| Flavor | oyster sauce | Optional depth-booster used in some Cantonese versions; adds seafood umami |
| Fat | sesame oil | Optional aromatic finish used in the no-cook stir-fry version (Source 2) |
| Aromatics | shiitake, cilantro, ginger, dried shallot, dried shrimp, star anise, Sichuan pepper, bay leaf, carrot | Optional 'vegetable water' (杂菜水) aromatics simmered into the base liquid (Source 1) |
| Seasoning | salt, chicken powder, white pepper | Optional seasoning adjustments per Source 2; fish sauce or MSG also acceptable per Source 1 |
Method
- 1Rehydrate dried shiitake mushrooms in warm water and reserve the soaking liquid as an umami-rich base.Mushroom water contributes free glutamate and round savory depth without requiring long simmering.
- 2(Optional) Combine the reserved mushroom water with cilantro, ginger, dried shallot, dried shrimp, star anise, Sichuan pepper, and bay leaf; simmer briefly to make 'vegetable water' (杂菜水).Pre-infusing the water with aromatics layers flavor before the soy sauces are introduced.
- 3Combine dark soy, light soy, water/vegetable water, sugar, and oyster sauce (if using); stir until the sugar fully dissolves.Sugar must dissolve completely for balanced sweetness and to avoid graininess in the finished sauce.
- 4Bring the mixture just to a boil, then immediately remove from heat.Source 1 explicitly warns that prolonged boiling alters the flavor; brief heat is sufficient to meld the ingredients.
- 5Cool completely; strain out any solid aromatics; transfer to a clean sealed bottle.Straining and using a sterilized vessel prevents spoilage and clarifies the finished base.
- 6Refrigerate and use as a dip, drizzle, stir-fry seasoning, or braising liquid as needed.Cold storage extends shelf life and allows the base to be reused across many dishes over multiple days.
Techniques that matter
Just-to-boil heating
Source 1 emphasizes boiling briefly only — over-simmering turns the flavor harsh and bitter.
Aromatic water pre-infusion
Steeping herbs and spices in the water component concentrates flavor without darkening the soy color excessively.
Strain and rebottle
Removes solids that would otherwise spoil and clarifies the sauce for clean dipping and finishing use.
Master-stock daily reboil (braising variant)
Source 4 reboils the master stock each day it is used, keeping it safe at room temperature for extended reuse.

Used in these dishes
Substitutions
- dark soy sauce (老抽) → Indonesian kecap manis — Adds sweetness and viscosity; reduce added sugar to compensate.
- light soy sauce (生抽) → Japanese koikuchi shoyu — Slightly sweeter and rounder; works but shifts profile away from Cantonese standard.
- oyster sauce → vegetarian mushroom oyster sauce — Preserves umami depth without shellfish; suitable for vegetarian/vegan cooking.
- granulated sugar → rock sugar (冰糖) — More traditional Cantonese choice; dissolves slowly but yields cleaner, rounder sweetness.
- shiitake soaking liquid → plain warm water — Loses the umami boost but remains functionally a valid base.
Troubleshooting
Sauce tastes harsh, bitter, or 'off'
Over-boiled or over-reduced — Source 1 explicitly warns prolonged heat degrades the flavor. → Discard and start a fresh batch; in future heat only just to a boil.
Sauce is too thin and lacks body
Too much water relative to soy, or insufficient reduction. → Reduce briefly over low heat, or increase the dark soy proportion in the next batch.
Sauce spoils within a few days
Contaminated bottle, inadequate straining of solids, or warm storage. → Use sterilized bottles, strain solids thoroughly, and refrigerate promptly after cooling.
Color too pale for a glaze-style application
Insufficient dark soy proportion. → Boost dark soy (or add a small amount of kecap manis) until a deep mahogany color is achieved.
