New here? This is the ninth article in our Banchan Deep Dive series: one Korean side dish per article. If Korean restaurants are new to you, start with Part 1 and Part 2 of the Survival Guide, then the rules for eating banchan. Last time we covered beoseot-muchim, the mushroom side dish English has no name for, which ended by asking whether something arriving in its own bowl is still a side dish. This article is that bowl.
Recipes vary by restaurant and household. When it matters, ask.
A Korean side dish is small. It is cool, or cold. It is usually a vegetable.
Five or six saucers of them arrive without being ordered. Nobody explains them. Nobody charges for them. By your second visit that has stopped being surprising.
Then, at a barbecue table, at a moment nobody at the table picked, a black stone pot lands.
It is not small. A dome of pale yellow stands up over the rim, moving slightly, still steaming. The pot is hot enough that touching it is a mistake you make exactly once.
It is not a vegetable either. It is eggs, and there are a lot of them.
It gets eaten fast. Nobody at the table can name it. Nobody asks.
The name is gyeran-jjim (계란찜). Two words. Egg, and the cooking method English translates as steamed.
The second word is the problem.
This article is about what is in that pot.
What the water is for, given that no two published recipes agree. Why a dish named for steaming is almost never steamed in a restaurant. Why it has to arrive that hot. And whether something that turns up in its own vessel, unasked, is still a side dish.
What is Korean steamed egg?
Korean steamed egg is gyeran-jjim (계란찜), eggs beaten with water or stock, seasoned with salt or with tiny salted shrimp, and cooked until they set. It arrives as banchan at Korean barbecue restaurants, usually very hot and at a moment the kitchen picks rather than your table, either in a black earthenware crock with the egg risen above the rim or in a plain bowl with a smooth flat top.
Is gyeran-jjim free at Korean barbecue?
Often, and not always. In the United States most people meet it as one of the side dishes that come with the meal unordered. It is also printed on the menu of an American Korean barbecue chain as an appetizer called steamed egg soup, and in Korea a chain built on extremely spicy tteokbokki sells it as a side for 2,000 won. If it has not arrived, ask whether it comes with your meal.
Why does Korean steamed egg puff up?
Two explanations are in print and neither is settled. One established recipe writer puts a teaspoon of baking powder in the ingredient list, while several others use no leavening at all, so a raised version is real without being the standard. The other explanation is steam from the water in the mixture, which is repeated constantly in Korea and has no published measurement behind it.
Is Korean steamed egg vegetarian?
Not reliably, and never vegan. Egg is the dish. The default seasoning is salted fermented shrimp, which is crustacean shellfish, and the liquid is often anchovy or kelp stock rather than water. Fish sauce and salted pollock roe are both ordinary. A salt and plain water version exists, which is exactly why this has to be asked rather than assumed.
What does gyeran-jjim taste like?
Mild, savory and salted, with texture carrying most of it. The seasoning is salt or salted shrimp rather than soy sauce, so it does not taste brown, and there is no chili in a standard version. English food writing describes the risen version as closer to biting into a cloud than to eating an omelet.
What is Korean Steamed Egg?
Gyeran-jjim is eggs beaten with water or stock, seasoned, and cooked until they hold the shape of whatever they were cooked in.
That is the whole object.
The eggs go through a sieve first. That takes out the stringy bits and the foam, and it is the difference between a surface you want to look at and one you do not.
Then they are beaten with the liquid until the two stop being two things. Then heat, from underneath or from around, until it stands up.
The seasoning is where it stops being an omelet. The default is saeu-jeot (새우젓), tiny shrimp salted and fermented whole. They season the egg and do something to it plain salt does not. Salted pollock roe is the other traditional route. Plain salt is common. Scallion and toasted sesame go on top.
If you find mushroom, peas, onion, zucchini or carrot in yours, they were chopped small enough to hang suspended instead of sinking.
The old way of making it is the one the name describes.
Soup or water comes up to heat and then down off the boil, on purpose, because a hard boil turns egg coarse. A bowl goes on top, wedged so it cannot rock, because a surface that moves while it sets will not set smooth.
The egg is beaten into the bowl. A lid goes over. Nothing touches a flame.
The one that comes up over the rim of a crock is light and airy under the spoon. Soufflé-like. Plenty of people call it exactly that: an egg soufflé.
It is banchan. Banchan are the small dishes that arrive at a Korean table without being ordered, and the rules for eating them got their own article.
This one sits at the edge of that category. It comes in its own pot. It arrives on the kitchen's clock instead of your table's. At some restaurants you are paying for it.
It is also not the egg you have already met on this blog. A bowl of galbitang arrives with thin ribbons of egg across the top. A plate of japchae has the same ribbons cut through it.
That is gyeran-jidan: egg cooked flat as a sheet, cooled and sliced. Same ingredient, opposite instructions. Jidan is thin enough to be a garnish. Jjim is thick enough to need the pot.
The Name Says Steamed. The Pot Does Not.
Jjim is a method word, and this blog has already defined it. The menu decoder files it under preparation: steamed or braised, cooked slowly in a closed pot until it gives up. The method exists for the cuts fire cannot fix. A jjim on the table means somebody spent an afternoon on you.
Now look at what is in this pot.
An egg has no connective tissue to melt and nothing in it that needs hours. And nobody spent an afternoon.
The published times are not close to an afternoon. One established Korean recipe prices three methods: five to seven minutes in the crock over direct heat, twelve minutes total in a double boiler, four to five in a microwave.
A second gives about two minutes of stirring plus two or three covered. The longest number anywhere is twelve, and most are under ten.
Then comes the part that breaks the word outright.
In the version that arrives risen over the rim of a black crock, nothing is being steamed.
Three separately published recipes for that version describe the same sequence, and none of it involves a steamer. Stock goes into the crock and boils over a direct flame. The beaten egg goes in on top.
Then somebody stands there and stirs. Constantly, for two to four minutes, until the mixture thickens and rises and is most of the way set. Only then does a lid go over, the heat drops, and two or three quiet minutes finish it.
That is a custard cooked in a saucepan by somebody who does not stop moving. The lid arrives at the end as a finishing tool, not as the method.
So the name fits two of the three. The smooth bowl really is steamed. So is the cafeteria pan. The thing you meet at a barbecue table is stirred over a fire, and the word on the menu is describing a cousin.
Which leaves the pot. The crock is a ttukbaegi, unglazed earthenware, and it is not presentation. It holds heat long after it leaves the flame, so the egg keeps cooking on the way to the table and after it lands.
This dish is at its best very hot, and the pot is the machinery that gets it to you that way.
Bob Miller owns a Weber kettle and has spent sixteen hours at a stretch arguing with it about heat. The black pot is the part of this dish he would have understood first. Same argument he makes every time somebody suggests foil.
The vessel is not a container. It is the last few minutes of the cooking.
That trick is older than the crock. The earliest recipe anybody can point to sits in a hand-copied Korean cookbook from the end of the sixteen hundreds, and it borrows its heat the same way.
One egg. Salted water measured out in eggshells, three of them. Two kinds of ground pepper. The mixture goes into a brass bowl, and the brass bowl goes on top of the cooking rice. The rice pot does the work.
No second fire. No second pot. The dish was assembled out of heat already being spent on something else, which is precisely what a microwave does for it now.
Two more things about that entry. The book gives the method and never names the dish, so the name it carries now was attached centuries later by researchers who read the instructions. And it is the first known Korean cookbook to carry the dish, which is not the same as the dish being invented then.
Absence from the surviving books is absence from the surviving books.
What the Water Is Doing
Every recipe puts liquid in. None of them agrees about how much, and the disagreement is not a rounding error.
One established Korean cooking site is exact: a quarter cup of liquid per egg, which it says is what gives you a silky custard.
A second, equally established, states a ratio. Eggs to liquid, one to one, with a reason attached: too much liquid makes the finished egg collapse quickly.
A third, printed by an American television kitchen, says traditionally there are fewer eggs and more liquid. That points away from both.
And the version that rises hardest uses the least. The ratio that circulates in Korea for the bomb style is two cups of egg to a third of a cup of water. That is barely wet at all.
It is tempting to line those up and hand you a rule. Less water, more lift.
Nobody has published that rule. What has been published is one reason running in one direction: too much liquid makes it fall. Everything else is a number with no argument attached, and nobody measured them against each other.
There is a second theory about the rise, and it has a harder edge, because it sits in an ingredient list. One of those same recipes calls for a teaspoon of baking powder. The others, including the American television one and both encyclopedia entries, carry no leavening at all.
Which settles less than it looks. It does not mean every tall crock has baking powder in it, and it does not mean none do. A leavened version is real, normal enough that a serious recipe writer prints it, and not the standard.
If the dome in front of you is unusually tall, there are two candidate reasons, and nobody at your table can say which.
What the sources do agree on is the liquid itself, and one of them puts it at the center. A recipe writer at an American newspaper says the liquid is what makes it worth having. Kelp stock, chicken stock, vegetable stock or plain water. One method, four different bowls.
Three Dishes, One Name
Ask for a picture of gyeran-jjim and you get three different objects back.
The first is the crock. In a set of forty seven Korean photographs of this dish, twenty eight were in a black earthenware pot or a stone bowl. About fifteen of those had a dome standing clear above the rim.
That is the picture the word brings up in Korea, and probably the one you have seen. The word a Korean search engine ranks first beside it is the word for bomb.
One correction, because English-language food writing has settled on a different word for it. Volcano.
In those forty seven photographs there was not one volcano. No crater. No vent. No opening of any kind. Every risen one was a smooth closed dome. The word is describing the height, not a hole.
The second is a plain bowl. Flat and smooth on top, no rise at all, closer to a set custard than to a soufflé. That is the home version and the microwave version, and the microwave is not a shortcut nobody admits to.
It ranks third on the list of things Koreans type next to this dish, well ahead of the double boiler. An American newspaper's recipe archive carries one.
The third is a square. School and workplace cafeterias make it in flat pans, steamed in bulk and cut into rectangles, with carrot and scallion set through the slab.
That version is not marginal. Korean search traffic carries the words for school meals and institutional catering beside the dish, and which of the three a Korean pictures first probably depends on where they ate it.
The tallest of the three is the newest. On Korea's largest recipe site, the first page of results for the bomb version carries nothing older than the middle of the twenty tens.
By the usual account a national cooking show ran an egg episode right at the start of that run and built the puffed crock version on air, and Korean media reprinted the recipe the next day.
Whether the broadcast made the shape popular or arrived while it was becoming popular, a page of search results cannot say, and this blog will not guess. What it can say is that the version English-language food writing treats as definitive looks younger than the bowl it displaced.
After that the variations run in every direction, and Korean search traffic names them. Cheese. Soft tofu. Mixed vegetables. Flying fish roe. One called snow flower.
Japanese style is on that list too. In Korea a Japanese-style steamed egg is filed as a kind of gyeran-jjim. A subhead, not a rival.
Ordering It and Eating It
It might be free and it might be a line on the bill, and the dish will not tell you which. In the United States you will most often meet it as banchan at a Korean barbecue restaurant, unordered.
It travels with a pot of doenjang-jjigae, the soybean paste stew, and the pair goes only to tables that ordered meat. Order a stew or cold noodles instead and you get neither. Those two are the hot corner of an otherwise cold spread.
An American Korean barbecue chain prints it under appetizers as steamed egg soup. In Korea a chain built on extremely spicy tteokbokki sells it as a side for 2,000 won.
Same bowl, three relationships with the check. If it has not arrived and you want it, ask whether it comes with the meal, not whether they have it.
Do not read anything into when it shows up. It is not cooked for your table. The kitchen makes several at once and sends the batch to every barbecue table still waiting, so where you land in the cycle is luck.
It can arrive before your meat does. It can turn up while you are busy at the grill.
At that same chain, some tables never get one from the kitchen. The round grill has a channel cut into its rim, and a server pours the raw egg straight into it. A table with a cold grill has no channel.
One arrival does mean something. The very end, after the meat is gone. Diners and restaurant people both read that as the kitchen having lost track of the table. Nothing arriving at all is a different event. The reason is usually what you ordered, not the kitchen.
Eat it first and eat it hot. Everything else on your table is built to wait. Kkakdugi, the cubed radish kimchi, is cold on purpose and will be exactly as good in twenty minutes. This one will not.
The crock is still cooking it. The texture is tightening while you decide. Whenever it landed, the clock started then.
It is the opposite of everything Bob Miller trained himself to do at a Korean table. Wait. Watch. Copy whoever knew more. This one does not wait for that.
Ask what is seasoning it, not whether it has shellfish in it. That distinction does real work for you.
💡 The shrimp you cannot see
Saeu-jeot is the default seasoning here and it is crustacean shellfish, one of the nine allergens American labels must declare. It also disappears. The shrimp are tiny, salted and fermented until they break down, and they go in before the egg sets, so a finished bowl shows nothing. Ask whether there is shrimp in it and you may get a truthful no from somebody looking at a plain yellow surface and thinking about whole shrimp. The question that works is what it is seasoned with, because the answer is a short list and whoever answers you has to say the word.
The liquid is the other hiding place. Anchovy stock instead of water. Fish sauce instead of salt. Salted pollock roe in its own right.
If fish is what you are ruling on, ask about the stock. A kitchen asked about the egg will answer about the egg.
Why This Dish Matters
Go back to the black pot landing on a barbecue table at a moment nobody there chose.
Everything about it reads as an event. The largest single object in your banchan spread. It stands up over its own rim. It arrives too hot to eat and refuses to wait.
It comes out when the kitchen is ready rather than when the table is, which in most cuisines is the privilege of the main course.
It is not the main course. It is a side dish built from the cheapest protein in the building, finished in under ten minutes, in a pot chosen because it holds heat, on a trick borrowed from a rice pot by somebody who never signed their name.
Bob can cook one thing at a competition level, and it takes him sixteen hours. This one takes under ten minutes and arrives looking like the bigger effort.
The gap between those two facts is the whole reason the crock exists.
Which answers the question the last article left open. Something that arrives in its own vessel is still a side dish. Rank at a Korean table is not settled by size, or by drama, or by what the kitchen spent.
It is settled by the job. This one's job is to be the hot thing. The radish kimchi's job is to be the cold one.
The pot goes back to the kitchen with a film of egg baked onto the inside of it. It was still hot enough to keep cooking after it was empty.
Next on this blog: Chuseok. The holiday has a date. This series does not. Jjim is egg thick enough to need a pot. On a holiday table the same egg is a coat on a pan, two hours of frying nobody is allowed to start early. A braise, a beef soup with cubes of white radish, and Bob Miller finding out what he volunteered for. Then kkakdugi, that radish cut into blocks instead of leaves.
