If you open a refrigerator in any home in Seoul, you will almost certainly find a stack of clear glass storage containers filled with banchan (Korean side dishes). Among the colorful kimchi jars and seasoned vegetables, there is usually a small container holding dark, shiny peanuts coated in a sweet and salty glaze. This is ttangkong jorim (sweet soy braised peanuts), one of the most beloved and comforting banchan in everyday Korean home cooking.

Unlike Western peanut snacks that are dry-roasted, heavily salted, or turned into spreadable butter, Korean braised peanuts are cooked low and slow in a soy-based liquid. The raw nuts absorb the savory, umbrella-like depth of soy sauce, garlic, and sweet syrup, turning plump, tender, and slightly chewy. In Korean homes, we eat ttangkong jorim as part of a daily meal alongside hot steaming white rice, soups, and other side dishes. It also makes a wonderful snack or a quick side dish packed into a lunch box because it holds up beautifully for weeks in the fridge.

Making authentic ttangkong jorim at home is remarkably simple, but many home cooks run into two common problems: the peanuts stay tough and rubbery, or the glaze turns into a hard, sticky mess that cements the peanuts together. My family formula relies on a classic Korean technique that guarantees tender peanuts wrapped in a glossy, silken glaze every single time.

Why This Works

• Parboiling raw peanuts first removes harsh skin astringency and softens the dense interior so the peanuts can absorb flavor easily during braising.
• Layering sweeteners at different stages—granulated sugar during the initial simmer for deep absorption, and rice syrup at the very end—creates a brilliant glass-like shine without turning sticky or hard when chilled.
• A short splash of neutral cooking oil coats the skins, preserving their smooth texture and preventing the reduced sauce from scorching or separating.

Ingredients

• 500 g (about 1.1 lbs or 3.5 cups) raw, unroasted peanuts (skin-on preferred)
• 1.2 liters (about 5 cups) water for boiling peanuts
• 360 ml (about 1.5 cups) water or light kelp stock for braising
• 60 ml (4 tbsp) Korean soy sauce (jin ganjang or all-purpose soy sauce)
• 45 ml (3 tbsp) Korean rice syrup (ssal-jocheong) or corn syrup (mulyeot)
• 25 g (2 tbsp) brown sugar or white granulated sugar
• 15 ml (1 tbsp) neutral cooking oil (such as vegetable, canola, or grapeseed oil)
• 2 cloves garlic, finely minced
• 15 ml (1 tbsp) toasted sesame oil
• 5 g (1 tbsp) toasted sesame seeds

Substitutions

If you cannot find raw peanuts with red skins intact, raw skinless peanuts work perfectly well. Avoid using roasted, dry-roasted, or pre-salted peanuts, as their texture and flavor profile will not endure the braising process. If Korean rice syrup (ssal-jocheong) or corn syrup is not available at your local store, honey or agave nectar makes a fine substitute, though you should slightly reduce the heat during the final glaze step to prevent scorching.

How to Make It

1. Parboil the raw peanuts to soften them. Rinse your raw peanuts thoroughly in cold water to clean off any soil dust. Place them in a medium saucepan and pour in 1.2 liters (5 cups) of fresh water. Bring to a rapid boil over high heat, then drop the flame to medium and simmer uncovered for 15 to 20 minutes. Parboiling is essential because raw peanuts are dense and woody; boiling breaks down the tough cell structure and leaches out excess astringent tannins from the skins. You will see the water turn a deep reddish-brown color.
2. Drain and rinse thoroughly. Drain the peanuts through a fine-mesh colander and discard the dark boiling liquid. Rinse the peanuts under cold running tap water for 30 seconds. This stops the cooking process instantly and washes away any lingering surface bitterness from the skin tannins.
3. Combine the initial braising ingredients. Return the drained peanuts to the pot. Add 360 ml (1.5 cups) of clean water, 60 ml (4 tbsp) of soy sauce, 25 g (2 tbsp) of sugar, 15 ml (1 tbsp) of neutral cooking oil, and the minced garlic. Stir everything together. Adding the oil now coats each nut and keeps the braising liquid cohesive as it reduces.
4. Simmer low and slow. Set the pot over medium-high heat until the liquid begins to bubble gently. Lower the heat to medium-low, cover the pot loosely with a lid left slightly ajar, and let it simmer gently for 20 to 25 minutes. Check occasionally and give it a quick stir. You want the liquid to reduce by roughly two-thirds while allowing the salty-sweet soy mixture to penetrate deep inside the peanuts.
5. Add the syrup for glaze and shine. Remove the lid completely. Pour in 45 ml (3 tbsp) of Korean rice syrup. Turn the heat back up to medium and stir continuously for 5 to 7 minutes as the liquid bubbles down into a glossy, thick syrup. Adding the dense syrup during the final reduction step coats the peanuts evenly and produces the iconic glass-like finish without cooking the sugars so long that they harden into candy. Stop stirring when there are only 2 to 3 tablespoons of syrupy liquid left at the bottom of the pot.
6. Finish with sesame oil and seeds. Turn off the heat completely. Immediately drizzle in 15 ml (1 tbsp) of toasted sesame oil and sprinkle 5 g (1 tbsp) of toasted sesame seeds over the top. Toss everything thoroughly so the fragrant sesame oil blends into the sticky glaze. The residual heat will wake up the nutty aroma of the sesame seeds without scorching them. Allow the peanuts to cool to room temperature before serving or storing.

Tips from a Korean Kitchen

In traditional Korean cooking, getting the texture right for braised side dishes (known generally as jorim) comes down to heat control and patience. Here are a few practical pointers to help you get consistent results in your own kitchen:

• Never skip the initial boiling step: Raw peanuts contain natural enzymes and tannins that make them hard and bitter if tossed straight into a soy sauce reduction. Boiling them first in plain water softens the texture so they absorb sauce rather than repel it.
• Differentiate your sweeteners: Sugar seasons the nut throughout the simmering process because its smaller molecules penetrate the peanut meat easily. Syrups (like ssal-jocheong) are thicker and create surface viscosity, coating the outside with a shiny varnish. Using both yields the best texture and appearance.
• Watch the pan during the final reduction: Syrups burn quickly once most of the water evaporates. Keep your spoon moving constantly during the last five minutes of cooking. If you see tiny dark wisps of smoke or smell caramel burning, pull the pan off the burner immediately.
• Taste for texture before turning off the stove: Peanuts should have a tender bite—soft enough to give easily, but firm enough to retain a pleasant chewy resistance. If they still feel uncomfortably hard before adding the syrup, add 3-4 tablespoons of extra water and continue simmering under a cover for another 5 to 10 minutes.

If Something Goes Wrong

Problem	Likely Cause	Fix
Peanuts remain tough or rubbery	Skipped or shortened the initial parboiling step	Add 1/2 cup of hot water or light stock to the pot, cover with a lid, and simmer on low for an extra 10–15 minutes before adding syrup.
Glaze hardens into a dense candy when chilled	Rice syrup was added too early or over-reduced	Warm the peanuts gently over low heat with 1–2 tablespoons of water to loosen the glaze, then store with slightly higher moisture.
Sauce tastes scorched or bitter	Syrup burned during the high-heat reduction phase	Keep the heat at medium-low during the syrup step and stir continuously; remove from heat as soon as 2–3 tablespoons of syrup remain.

Scaling & Make-Ahead

Scaling: If doubling the batch, keep the parboiling time roughly the same (15–20 minutes), but increase the low-and-slow braising time by 5–10 minutes to allow the larger liquid volume to reduce evenly into a glossy glaze.

Make-Ahead: Parboil, drain, and rinse the peanuts up to 24 hours in advance. Store them covered in the refrigerator, then proceed directly to step 3 when you are ready to braise.

Storage

Ttangkong jorim is a classic example of a long-lasting Korean side dish (mit-banchan). Transfer the cooled peanuts along with any excess pan glaze into a clean glass airtight container. Store it in the refrigerator, where it will keep fresh and flavorful for up to 3 weeks.

Because of the rice syrup and high soy content, the glaze will thicken slightly when cold. You can eat these peanuts straight out of the fridge.

Key Takeaways

• Parboiling raw peanuts in plain water removes astringent tannins and breaks down tough textures so the nuts absorb seasonings evenly.
• Stagged sweetness—sugar early during simmering for deep flavor, and rice syrup late for surface sheen—creates a non-hardening, glass-like finish.
• Adding a tablespoon of neutral oil keeps the glaze emulsion stable and prevents scorching during final reduction.
• This resilient mit-banchan stores beautifully in the refrigerator for up to 3 weeks without losing its glossy coating or tender bite.
