Jungkook's Buldak Noodle Recipe That Broke Korean Search Engines

Have you ever watched a man make noodles at 6 AM on a livestream and thought, "I need to make that right now"?

That's exactly what happened when BTS's Jungkook casually started cooking during a Weverse live in April 2023. He wasn't promoting anything. He wasn't following a script. He was just... hungry. And what he made — a spicy, nutty, cold buckwheat noodle dish he invented himself — sent Korean search engines into a meltdown within hours.

The dish is called 꼬소한 불마요 들기름 막국수 — Toasty Buldak Mayo Perilla Oil Makguksu. Yes, he named it himself. And yes, it's as delicious as it sounds.

The Recipe

Here's the full recipe, exactly as Jungkook shared it — with some notes for international ARMY trying to find the ingredients.

Jungkook's Buldak Perilla Oil Makguksu

The Sauce:

• 4 tablespoons perilla oil (들기름) — must be cold-pressed, 100% pure. Jungkook specifically said the golden-colored one, not the dark brown kind.
• 2 tablespoons Cham sauce (참소스) — a Korean dipping sauce, lighter and slightly sweeter than soy sauce.
• 1 tablespoon Buldak sauce (불닭소스) — Samyang's famous fire sauce.
• 1 tablespoon Buldak mayo sauce (불닭마요소스) — the creamy version.
• 1 egg yolk — "Take out the stringy white part!" Jungkook insisted.

Mix everything together. That's your sauce.

Jungkook's Upgrade (shared the next day):

• ¼ onion, finely diced
• 1 tablespoon chili flakes (고춧가루)
• ½ tablespoon minced garlic
• Ground roasted sesame seeds

"Even more delicious!" he wrote on Weverse.

The Noodles:

Korean buckwheat noodles (메밀면) — at least 30% buckwheat flour. NOT Japanese soba. NOT naengmyeon noodles. Boil for about 5 minutes, then rinse thoroughly under cold water — "챠챠챠챠챠!" as Jungkook described — to remove all the starch. Drain well.

Assembly:

Toss cold noodles with sauce. Top with 김자반 (gimjaban) — seasoned seaweed flakes. NOT regular dried seaweed. Jungkook was very firm about this: "Not gimgaru! Gimjaban only!!!" Add egg yolk on top and mix everything together.

For International ARMY — Ingredient Substitutes

Perilla oil: Available at Korean/Asian grocery stores or online (Amazon, H Mart). If truly unavailable, toasted sesame oil works as a substitute, but the flavor will be different.

Cham sauce: Look for "CJ Beksul Cham Sauce" at Korean stores. If you can't find it, mix: 3 tablespoons soy sauce + 1 tablespoon vinegar + 1 tablespoon sugar + a splash of lemon juice.

Buldak sauces: Samyang Buldak sauces are widely available internationally. Check the Asian aisle at major supermarkets or order online.

Buckwheat noodles: Look for packages labeled "makguksu" (막국수) or Korean buckwheat noodles.

Gimjaban: Available at most Korean grocery stores. In a pinch, crush up seasoned seaweed snack sheets.

Why This Recipe Is Special — A Korean Perspective

What is makguksu?

Makguksu (막국수) literally means "right-away noodles." Mak means "just throw it together," and guksu means noodles. It's a traditional dish from Gangwon Province — Korea's mountainous northeastern region — made with cold buckwheat noodles, typically served in summer with a tangy, vinegary sauce.

In Korea, makguksu is comfort food. It's what you eat on a hot day when you don't want anything heavy. It's simple, refreshing, and humble.

What makes Jungkook's version unique?

Traditional makguksu sauce is vinegar-based — tangy, light, sometimes spicy with gochujang. Nobody — and I mean nobody — had combined Buldak fire sauce with perilla oil for makguksu before Jungkook did.

Buldak sauce is aggressively spicy. Perilla oil is mellow and earthy. On paper, they shouldn't work together. But Jungkook figured out that the fat in perilla oil tames the Buldak heat, while the egg yolk adds creaminess that ties everything together.

As a Korean who has eaten makguksu my entire life, I'll be honest: when I first heard the combination, I thought it was weird. But I tried it — and it works. It's spicy but not painful, rich but not heavy, and the cold noodles make it oddly refreshing. Jungkook might actually have a real talent for flavor.

The impact was insane:

Within hours of his livestream, "들기름 막국수" (perilla oil makguksu), "막국수 레시피" (makguksu recipe), and "불닭소스" (Buldak sauce) trended in 155 countries. Korean supermarkets reported spikes in perilla oil sales. Restaurants even began adding "Jungkook-style makguksu" to their menus. This wasn't just a fan trend. It crossed over into mainstream Korean food culture.

Notice a pattern? Almost every single restaurant is a Korean BBQ joint. Jungkook's taste is very "Korean man" in the best way — he loves meat, grilled over charcoal, with soju on the side. This isn't celebrity fine dining. These are the kinds of places Korean friends go for a Friday night out. And honestly? That's what makes his recommendations trustworthy.
