Start With the Takeaway Shelf, Not the Recipe
Most of us in the UK met Chinese food through a paper bag: a foil tray of sweet and sour, a plastic tub of chilli oil we never quite finished. The good news is that the sauces behind those flavours are cheap, widely stocked in British supermarkets and Asian grocers, and they do far more than dress a takeaway. Learn five or six of them properly and you can cook a decent Chinese meal on a Tuesday night with whatever is in the fridge. The trick is understanding what each one is for — salt, colour, sweetness, depth or heat — rather than treating them all as interchangeable brown liquids.
Light Soy and Dark Soy Are Not the Same Thing
This is the single most useful distinction in the cupboard. Light soy sauce is the salty one. It is thin, brown, and it does the seasoning in your stir-fry, your marinade, your steamed fish. Despite the name, it is not low in salt — "light" refers to its colour and body.
Dark soy sauce is thicker, slightly sweet, aged longer, and much less salty. It is a colourant and a flavour-builder, not a seasoning. A teaspoon in a braise or a plate of noodles gives that glossy, deep mahogany look. Use it by the spoonful, never by the glug. If you season only with dark soy, the dish turns black and tastes flat.
- Light soy: seasoning, marinades, dipping, fried rice.
- Dark soy: braises, noodles, red-braised pork, colour.
- Mushroom soy: dark soy infused with mushroom — excellent for vegetarian braises and noodle sauces.
- Seasoned soy for sushi is a different job entirely; keep it for dipping.
Hoisin, Char Siu and the Sweet Sticky Family
Hoisin is sweet, thick and fermented, with garlic and a hint of five spice. It is not just a dipping sauce for pancakes. Thin it with a splash of rice vinegar or Shaoxing wine and it becomes a glaze for chicken wings, pork ribs or aubergine. Because it is sugary, it catches and burns quickly — add it in the last minute of cooking, or brush it on and finish under the grill.
Char siu sauce is hoisin's sweeter, redder cousin, built for roast pork and handy on roast chicken thighs. Plum sauce is fruitier and sharper, the classic partner for duck and spring rolls. All three live happily in the fridge once opened and will keep for months.
Bean Pastes: Where the Real Depth Comes From
If your cooking tastes thin and one-dimensional, this is usually the missing layer. Bean pastes are fermented, salty and savoury in a way soy sauce alone cannot achieve. Fry them briefly in oil before adding anything wet — thirty seconds is enough — and their flavour opens up dramatically.
- Sweet bean sauce (tianmianjiang): thick, dark, gently sweet. The one for Peking duck pancakes and zhajiangmian noodles.
- Yellow bean paste: robust and salty, brilliant in braises and with minced pork.
- Chilli bean paste (doubanjiang): Sichuan's backbone. Fermented broad beans and chillies, deep red, hot and funky. Essential for mapo tofu.
- Black bean sauce in jars: garlicky and salty, ready to go. Superb with beef and green peppers, or clams.
- Fermented bean curd: small jars of soft, salty cubes. Mash half into a marinade or stir through blanched greens.
Chilli Oil, Chilli Sauce, Chilli Bean — Know the Difference
Heat is not one ingredient. Chilli oil is mostly about aroma: infused oil with crisp flecks of chilli, sometimes sesame and peanut. It is a finishing condiment — spoon it over noodles, dumplings or cold cucumber. Chiu chow style is garlicky and mild, ideal if you want flavour without much burn. Chilli garlic sauce is sharper, often vinegar-forward, and works stirred into fried rice or noodles at the end. Doubanjiang is a cooking paste, not a table sauce — it goes into the wok, not onto the plate.
A dish usually wants only one or two of these, added at different moments. Cooking heat goes in early; finishing heat goes on at the table.
Putting It Together: A Simple Order of Operations
The sequence matters more than any single recipe. Heat your wok until it is properly hot, add oil, then aromatics — garlic, ginger, spring onion whites. Next, any fermented paste, fried for half a minute. Add your protein, then vegetables. Splash in light soy with a little water or stock. Add dark soy last for colour. Sweet sauces like hoisin go in at the very end so they do not burn. Chilli oil comes off the heat or at the table.
Then taste. If it is too salty, a pinch of sugar rounds it off. If it tastes dull, a few drops of rice vinegar or black vinegar will lift it. If it lacks depth, you probably needed more paste, not more soy. Store soy sauces in a cool cupboard, and move hoisin, bean pastes, chilli bean paste and fermented bean curd to the fridge once opened — if a paste separates, just stir the oil back in. That is the whole guide. Everything else is practice.
