Korean soy sauce

Taste and Texture

The saltiness is clear, with the savory aroma and umami characteristic of fermented soybeans. The liquid itself is clear and thin, and when added to food, it tends to season the entire broth rather than coating the ingredients. The color is relatively light, but if used in larger quantities the broth color can become muddy or dark. In delicate clear broths, even a small amount is noticeable, so dividing it with salt allows more precise flavor control.

Main uses

• Add to broth dishes like mu guk (radish soup), kongnamul-guk (bean sprout soup), miyeok-guk (seaweed soup), doenjang-guk to enhance depth beyond what salt alone provides.
• When salting namul (seasoned greens) such as spinach or bracken, a small amount added can contribute saltiness and the savory aroma.
• It can be used as a seasoning base for braises like tofu braises or fish braises, but for braises where dark color and strong sweet-salty seasoning are central, using other soy sauces along with it is more natural.
• When finishing soups or stews, it is convenient to adjust the flavor by considering the moisture released from ingredients and adding only as needed.

Preparation tips

• Shake the bottle lightly before use to check the flavor, but there is no need to shake vigorously just because there may be sediment. Depending on the product, fermentation components or fine sediments may be present, so if you want a clear broth, carefully pour from the top part. For broth dishes, don't add the full amount initially; start with about half, simmer, and then adjust the seasoning. If the liquid reduces or ingredients release salinity, it can become saltier than expected.
• When dressing namuls, instead of pouring guk-ganjang directly in large amounts, mix it first with sesame oil, minced garlic, and sesame seeds and toss in small amounts to prevent uneven salting.
• If you fry garlic or scallions in oil, do not burn guk-ganjang for a long time, as it can turn rough and bitter. If you want roasted aroma, lower the heat and simmer a small amount at the edge briefly before adding other liquids.

Cooking characteristics

• When added to boiling broth, the saltiness and fermented aroma spread quickly, and as it boils longer, the raw soy sauce aroma becomes mellow. However, as the broth reduces, the saltiness becomes higher, so in long-simmered stews it's safer to leave some seasoning to adjust at the end.
• In clear broths, adding a small amount can deepen the base flavor more than salt alone. However, adding too much can let the soy aroma dominate over the sweetness or aroma of ingredients, so for pale ingredients like radish or clams, restraint is especially important.
• Pairs well with acidic ingredients or with gochugaru, but guk-ganjang itself does not provide much sweetness. When making a spicy-sweet glaze, design the sweetness and color separately.
• When used as a base seasoning for meat or fish marinades, the surface gets seasoned quickly, but the longer you marinate, the more moisture evaporates and the texture can become firm. Short marinating or using a method that includes moisture from water, stock, or vegetable juice in the marinade may be more suitable.

Good combinations

• Pairs well with pale, moist ingredients like radish, cabbage, bean sprouts, tofu, and mushrooms, where guk-ganjang’s savory depth fills the broth’s empty taste.
• Using with minced garlic, scallions, sesame oil, and sesame seeds creates a familiar savory aroma for namuls and tofu dishes.
• With dashi made from dried anchovies and kelp or with shellfish stock, use less guk-ganjang and fine-tune with salt. If both are combined, the umami may be overwhelmed by saltiness.
• In soups or stews that use chili flakes, guk-ganjang can form the flavor base, but does not replace the color and sweetness provided by other seasonings.

Points to consider when substituting

• When guk-ganjang is not available, use light soy sauce or cooking soy sauce in small amounts and finish with salt. However, the color may become darker or the aroma may differ, so start with about half the amount and taste gradually.
• Regular jin-ganjang may have more color, sweetness, and viscosity, so it may not be suitable as a substitute for clear soups. For dishes where a clear color is important, complement with broth or minced garlic and scallions to enrich flavor instead of direct substitution.
• In namul, you can blend a small amount of salt with cooking soy sauce, but differences in salinity and sweetness between products are large, so adjust the ratio according to the amount of moisture in the dish and other seasonings.
• For braises that require a deep color and gloss, use guk-ganjang not as a full substitute for jin-ganjang, but use guk-ganjang only for part of the saltiness and combine jin-ganjang or cooking soy sauce for a better balance.
