Recipes with Soy Sauce

Soy sauce is the backbone of savoury seasoning across East and Southeast Asia, a fermented brew of soybeans, wheat, salt and water that delivers deep, salty umami in a single splash. Brewed and aged over months, a good naturally fermented soy sauce carries far more complexity than its colour suggests, layering roasted, malty and faintly sweet notes beneath the salt.

What it is and how it tastes

At its core soy sauce is salt made savoury. The long fermentation breaks soy proteins down into glutamates, the compounds responsible for that mouth-filling umami, while the wheat contributes a gentle sweetness and aroma. Cheaper sauces made by rapid chemical hydrolysis taste flatly salty and slightly harsh; naturally brewed bottles are rounder, more fragrant and worth the small premium. Colour ranges from the bright reddish-brown of a light soy to the near-black of an aged dark soy, and the flavour shifts accordingly. A good soy sauce should taste salty but layered, with roasted and faintly sweet notes lingering after the salt rather than a single sharp hit.

How to use it

Soy sauce works at every stage of cooking. Stirred into marinades it seasons and tenderises; added to a hot wok it caramelises against the metal and lifts a stir-fry with a savoury, slightly smoky edge. A few drops finish a soup or a bowl of rice, while braises lean on dark soy for a glossy, mahogany glaze. Add it toward the end of high-heat cooking to keep its aroma, or early in a slow braise where time mellows it. A common Chinese approach is to use the two together, light soy for the salt and a smaller measure of dark soy for the colour, so the dish is both well seasoned and richly hued. Because it is already salty, taste before adding extra salt elsewhere, and remember that the sauce reduces and concentrates as it cooks.

Buying and storing

Look for bottles listing simply soybeans, wheat, salt and water, ideally noting natural brewing or fermentation, and avoid those padded with caramel colouring and corn syrup. Decide whether a recipe wants light soy for seasoning or dark soy for colour, and ideally keep both on the shelf since they are not interchangeable. Once opened, store in a cool cupboard or, better, the fridge to preserve aroma, and use within a few months while the flavour is at its brightest.

Where it shines and substitutes

Soy sauce is indispensable to a sticky teriyaki salmon glaze, to the dipping sauce for pork gyoza, and to the seasoning of a savoury pork fried rice. When a gluten-free version is needed, tamari is the closest match; coconut aminos is milder and sweeter. For more on stocking the essentials it anchors, see the Asian pantry guide.
