Soy Sauce
Soy sauce is a fermented condiment brewed from soybeans, wheat, salt, and a koji culture, delivering deep umami and saltiness across Chinese, Japanese, Korean, and Southeast Asian cooking and well beyond.
How to buy
Look for naturally brewed soy sauce -- labeled 'brewed' and listing soybeans, wheat, salt, and koji -- rather than chemically hydrolyzed versions, which taste flatter and harsher. Regular (light) soy sauce is thinner and saltier; dark soy sauce is aged longer, thicker, and slightly sweet, used more for color than seasoning. Tamari is a wheat-free option worth seeking out for gluten sensitivities.
How to store
Soy sauce keeps well in a pantry unrefrigerated for a long time thanks to its salt content, though refrigerating it after opening preserves flavor and slows gradual darkening over many months. Keep the cap tight to limit oxidation.
Culinary profile
- Flavor
- Salty and deeply umami, with notes of roasted grain, a touch of caramel, and a light fermented funk. Dark soy sauce adds sweetness and color without piling on more salt, while light soy sauce reads sharper and saltier on its own.
- Texture
- Thin and watery for regular or light soy sauce; dark soy sauce is noticeably syrupy, clinging to food and helping it coat stir-fries and glazes evenly.
- Aroma
- Savory, slightly sweet, roasted-grain aroma from fermentation; dark soy sauce carries a faint molasses-like note on top.
How to prepare
- Marinade base — Combined with garlic, ginger, and sugar to season meats and tofu before cooking.
- Dipping sauce — Mixed with vinegar, chile, and scallion as a dip for dumplings and sushi.
- Glaze — Reduced with sugar or mirin into sticky, savory-sweet glazes.
- Finishing seasoning — Drizzled along the hot edge of a wok or pan for a quick burst of smoky flavor in stir-fries.
