Korean Food Secrets: The Frozen Pork Belly That Curls Like Wood Shavings (And Sparked a Courtroom Fight)

 

Tonight's dinner curled up on the grill like shavings off a carpenter's plane. That's not a metaphor. That's literally what it's called — daepae samgyeopsal, 대패삼겹살. Paper-thin. Frozen. Gone from the grill in under a minute.

I ordered it again tonight. And while it sizzled, I remembered something: this particular corner of Korean food just survived a courtroom fight over who actually invented it.

The quick answer: Daepae samgyeopsal is frozen pork belly, shaved paper-thin on an industrial meat slicer until it curls like wood shavings. Because it starts frozen instead of fresh, it can be mass-produced at a uniform thickness — which makes it cheaper than fresh pork belly. It cooks in seconds, and that's exactly why it's a fixture at Korean group dinners and drinking sessions.

1. What Frozen Samgyeopsal Actually Is

The Frozen Pork Belly

Korean food splits pork belly into two camps: fresh, chilled belly (saeng samgyeopsal), and frozen belly (naengdong samgyeopsal).

Frozen samgyeopsal isn't fresh meat. It's sliced while still frozen, on an industrial meat slicer. That's the trick. Slicing frozen meat lets producers cut it to a perfectly uniform thickness, at scale. Fresh meat can't be sliced that precisely by hand, not at that volume. That's why frozen samgyeopsal costs less than fresh — cut for cut.

2. Daepae Samgyeopsal vs. Regular Frozen Samgyeopsal

Most people use these two names interchangeably. They shouldn't.

Regular Frozen Samgyeopsal Daepae Samgyeopsal

Thickness	Thin, but doesn't curl	Sliced so thin it curls like wood shavings
Texture	Standard grilled pork belly	Paper-thin, almost delicate
Cook time	Fast	Seconds

Here's the straight answer: daepae samgyeopsal is a subset of frozen samgyeopsal. Only the cuts sliced thin enough to curl earn the name.

3. Why It's Cheap — and Why Koreans Love It

Three reasons, no fluff:

• Production. Frozen meat sliced by machine beats hand-cut fresh meat on cost, every time, at scale.
• Speed. Thin meat cooks fast. Fast means everyone at the table eats at the same time — which is exactly why it's a staple at Korean work dinners (hoesik) and drinking spots.
• Price. One large-mart promotion had imported frozen daepae samgyeopsal at roughly 1,298 KRW per 100g (~$0.90), against roughly 1,680 KRW (~$1.20) for fresh Korean chilled belly. (Converted at about 1,400 KRW to the dollar. Treat these as a snapshot, not a fixed price — it moves by store, season, and sale.)

People eat it wrapped in lettuce with minari and shredded scallion. Or, since it's so thin, they skip the lettuce and wrap it straight around a spoonful of rice.

4. The Courtroom Fight Over a Korean Food Icon

Here's where it gets genuinely interesting.

Baek Jong-won — the restaurateur known internationally as a judge on Culinary Class Wars — has claimed for years, across multiple broadcasts, that he invented daepae samgyeopsal in 1993. His story: he meant to buy a meat slicer, bought a ham slicer by mistake, ran frozen pork belly through it, and watched the meat curl up like wood shavings. He trademarked the name in 1998.

That story just took a hit in court. A YouTuber — a former journalist — presented evidence that daepae samgyeopsal, under that exact name, was already popular in Busan's Choryang neighborhood back in the late 1980s, years before Baek's version. A franchise owner sued the YouTuber for damages, arguing the videos hurt sales. The court sided with the YouTuber. Judges found that daepae samgyeopsal appears to have been trending in Busan since the late 1980s, before Baek ever sold it, and that a 1993 newspaper clipping his side used as proof was actually about an unrelated restaurant.

None of this should be shocking. Daepae samgyeopsal doesn't require any special technique. Korea's samgyeopsal boom also started in the 1980s, back when fresh pork belly wasn't cheap or easy to find. Running frozen meat through a slicer wasn't a stroke of genius — it was the obvious move, and it likely happened independently in more than one city.

Credit where it's due: the trademark is real, and turning "daepae samgyeopsal" into a nationwide, franchise-scale name was Baek's doing, even if he didn't invent the dish. He may not be the inventor. He's still the reason you know the name.

5. Field Notes: Timing and the Foil Trick

Straight from tonight's table:

• Line the grill with foil. Daepae samgyeopsal is thin enough to stick to a bare grill plate almost instantly. Korean restaurants get around this with a sheet of cooking foil laid over the grill. Do the same at home — it's a small trick that solves a real problem.
• Timing is everything. This meat has already been frozen once, so it loses moisture fast the second it hits heat. Overcook it even slightly and it turns chewy. It's thin, so the window is short. The moment the color changes, flip it.

Tonight's sides were butter soy sauce rice and yeolmu noodles. I've already covered yeolmu noodles. Butter soy sauce rice gets its own post next.

6. FAQ

Does frozen pork belly taste worse than fresh? Not worse — different. It's thinner and more delicate, but it trades away some of the juiciness you get from a thick cut of fresh belly.

Did Baek Jong-won really invent daepae samgyeopsal? Legally, no. A Korean court ruled he wasn't the originator, pointing to Busan's Choryang neighborhood serving it since the late 1980s. He did trademark the name in 1998, and he's largely responsible for turning it into a national menu item.

What's the single most important tip for cooking it at home? Foil on the grill, and flip the second the color changes. A few extra seconds turns it tough.

How do Koreans usually eat it? Wrapped in lettuce with minari and shredded scallion — or, since it's so thin, wrapped straight around a spoonful of rice.

7. The Bottom Line

Daepae samgyeopsal isn't just cheap pork belly. It's a byproduct of frozen-meat distribution and the nationwide spread of industrial meat slicers — a genuinely Korean food story, even if nobody can quite agree on who deserves the credit. Next time you're at a Korean BBQ spot, order it, ask for foil on the grill, and cook it fast.

Three-line takeaway:

1. Daepae samgyeopsal is frozen pork belly sliced so thin it curls like wood shavings — frozen, not fresh, which keeps it cheap and easy to mass-produce.
2. Baek Jong-won trademarked the name in 1998, but a recent court ruling says he wasn't the inventor — Busan was serving it since the late 1980s.
3. It's thin and already been frozen once, so cook it fast and flip the moment the color turns, or it gets tough.
