INGREDIENT KNOWLEDGE

Soy Sauce

Soy sauce is a fermented seasoning that contributes salt, umami, aroma, colour, and complexity. Different regional styles are not interchangeable in every recipe.

What Is Soy Sauce?

Traditional soy sauce is produced from soybeans, often wheat, salt, water, and fermentation cultures. Brewing and aging create amino acids, sugars, acids, and aromatic compounds that give the sauce far more complexity than salt alone.

Common Styles

Chinese light soy is generally thin and seasoning-focused; Chinese dark soy adds deeper colour and some sweetness. Japanese koikuchi is an all-purpose brewed style, while usukuchi is lighter in colour but not necessarily lower in salt. Tamari, Korean ganjang, Filipino toyo, and other regional sauces have distinct production traditions and flavours.

How to Choose and Store

Choose the style specified by the cuisine when authenticity matters. Read labels for brewing method, sweetness, sodium, and added flavourings. Store unopened according to the manufacturer; refrigeration after opening helps preserve aroma and colour in many brewed sauces, especially over longer periods.

Cooking with Soy Sauce

Use it in marinades, dipping sauces, stir-fries, braises, soups, glazes, fried rice, noodles, and dressings. Account for its salt before adding additional seasoning. Long cooking softens fresh fermented aromas, while a small final addition can restore fragrance.

Pairings and Substitutions

Soy sauce pairs with ginger, garlic, sesame oil, rice vinegar, chilli, scallion, sugar, mushrooms, meat, seafood, tofu, and noodles. Tamari can replace many soy sauces but tastes different. Fish sauce contributes salt and umami but has a completely different aroma.

Common Mistakes

• Assuming dark soy is simply stronger light soy.
• Adding salt before accounting for soy sauce.
• Using one national style for every Asian recipe.
• Pouring heavily instead of seasoning in stages.
