📝 About This Recipe
Jin-ganjang is the crown jewel of Korean soy sauces, traditionally aged for years to achieve a dark, syrupy consistency and a complex profile of sweet and savory notes. This 'brewed' style of soy sauce is less salty than its counterparts, boasting a rich depth of flavor derived from slow-simmering with aromatics. It is the essential secret ingredient for creating the perfect glaze on Galbi or adding a soulful backbone to authentic Korean braises.
🥗 Ingredients
The Foundation
- 4 cups High-quality Soy Sauce (Preferably naturally brewed 'Yangjo-ganjang')
- 2 cups Water (Filtered water is best)
- 1/2 cup Cheongju (Korean refined rice wine; dry sake is a good substitute)
Aromatic Infusion
- 2 pieces Dried Kelp (Dashima) (Approximately 4x4 inches each)
- 5-6 pieces Dried Shiitake Mushrooms (Adds intense earthy umami)
- 1 large Yellow Onion (Halved, with skins left on for color)
- 10 pieces Garlic Cloves (Slightly smashed)
- 2 inches Ginger (Sliced into thick coins)
- 3-4 stalks Green Onions (Use the white and light green parts)
- 2 pieces Dried Red Chili (Whole, for a subtle warmth)
Sweetness & Complexity
- 1/2 Korean Pear (Sliced; provides natural enzymes and sweetness)
- 1/2 Apple (Sliced; adds a bright acidity)
- 1/2 cup Brown Sugar (Packed; for deep caramel notes)
- 1/4 cup Grain Syrup (Jocheong) (Can substitute with honey or corn syrup for shine)
- 1 teaspoon Whole Black Peppercorns (Whole)
- 1/2 Lemon (Sliced; added at the very end for freshness)
👨🍳 Instructions
-
1
Thoroughly wipe the dried kelp (dashima) with a damp cloth to remove any excess white powder, but do not wash it under running water.
-
2
In a large, heavy-bottomed stockpot, combine the soy sauce, water, and rice wine (cheongju).
-
3
Add the onion halves, smashed garlic, ginger slices, green onions, dried chilies, and black peppercorns to the pot.
-
4
Stir in the brown sugar and grain syrup until partially dissolved, then add the dried shiitake mushrooms, pear slices, and apple slices.
-
5
Bring the mixture to a gentle boil over medium-high heat. Watch closely to ensure the soy sauce doesn't foam over the sides.
-
6
Once boiling, add the prepared kelp (dashima). Let it simmer for exactly 10 minutes, then remove the kelp with tongs to prevent the sauce from becoming slimy.
-
7
Reduce the heat to low and let the sauce simmer uncovered for 1 hour. This slow reduction concentrates the flavors and creates the 'Jin' (deep) characteristic.
-
8
After 1 hour, the liquid should have reduced by about one-third. Turn off the heat.
-
9
Add the fresh lemon slices to the hot liquid and let the entire mixture steep and cool completely at room temperature.
-
10
Once cooled, strain the sauce through a fine-mesh sieve lined with cheesecloth into a clean bowl, discarding the solids.
-
11
Transfer the finished Jin-ganjang into sterilized glass bottles or jars.
-
12
Store in the refrigerator for at least 24 hours before using to allow the flavors to harmonize and mature.
💡 Chef's Tips
Use the leftover simmered shiitake mushrooms from the sauce; they are delicious when sliced and added to stir-fries. If the sauce tastes too salty, add a few more slices of Korean pear and simmer for another 10 minutes. Always use a stainless steel or ceramic pot; reactive metals like aluminum can give the soy sauce a metallic tang. For a vegan version, ensure your grain syrup and soy sauce are certified vegan-friendly. This sauce keeps beautifully in the refrigerator for up to 6 months due to its high salt and sugar content.
🍽️ Serving Suggestions
Use as the primary base for Galbi-jjim (braised short ribs) for a professional-grade depth of flavor. Drizzle over a warm bowl of egg fried rice with a pat of butter for a quick, comforting meal. Combine with sesame oil and toasted sesame seeds to make a premium dipping sauce for Mandu (dumplings). Brush onto grilled salmon or tofu during the last 2 minutes of cooking for a glossy, savory glaze. Mix a tablespoon into vegetable stir-fries to provide a rich 'wok-hei' style finish without the high heat.
