Yukgaejang 육개장 (Spicy Beef Soup with Vegetables)

So, one of the annual events that most Jejuites take part in is the picking of wild gosari, or bracken fiddleheads. They are a prized ingredient here on Jeju with the wild varieties being rich in calcium, protein, and dietary fiber. They are so important that ajummas and halmonis (actually most Jeju elderly) scour the mountainside in search of the long, unique looking fern that make itself available in spring. My partner and I got to experience our first gosari picking with the help of a local friend, who happens to be so good at finding and picking enough gosari to sell at the market. Note: our friend even closes his popular curry restaurant during the short picking season to make some extra income. Luckily for us newbies, we learned quickly from our veteran friend and picked just enough to prepare one of my favorite soups, yukgaejang (spicy beef soup with vegetables).

I have fond memories of yukgaejang during my childhood. I remember my mom would cook a huge pot of this spicy soup with a lot of stringy beef brisket, lasting us days if not weeks on end. The best part about this soup is the chunkiness and the harmonious nature of the ingredients. You have the long strands of shredded brisket with the equally long pieces of leeks or scallions, gosari, and bean sprouts that make it a hearty, lumberjack of a meal. Another aspect that makes it unique is the gosari itself, providing another interesting texture to the dish while at the same time giving the broth a deep earthiness. Needless to say, I couldn’t get enough of this soup as a kid, and I’m so glad that I could reconnect to it by having wild gosari to work with for this particular batch.

Note: Most likely you will not have wild gosari to cook with, but dried gosari will be sold in packages at most Korean markets and Asian grocers. Simply rehydrate by a soaking in water for at least 30 minutes before boiling in the soup. Gosari can also be used as a popular side dish called gosari namul, where it’s boiled and then sauteed with few seasonings. You might have seen it in a bowl of bibimbap.

Another note: Substitute the beef with chicken and you have dak yukgaejang, providing an even healthier alternative to the traditional, classic dish. In Jeju Island, yukgaejang is made with pork in a thick broth similar to momguk. Here’s a great article featuring the two dishes explained by Yang, Yong Jin, a Jeju cuisine expert and someone I had the pleasure of meeting recently.

Driving about 15 minutes inland from the shore, our friend thinks this is where the gosari lay hidden. And he’s right.
We found some fiddlehead ferns just as we made our way through the weeds and bushes.
Can you see the gosari?
Here’s how much we collected that day. Definitely enough to make a big pot of yukgaejang.
After rinsing well under cold water, boil with a small amount of salt for at least 15 minutes.
Spread out in a well-ventilated area and set out until completely dry.
Here are the ingredients for yukgaejang after drying the gosari for a few days.
The only irking part was the price of this small cut of hanwoo (domestic) beef for nearly 10,000 won ($10 dollars). I can only imagine how much meat (i.e brisket) I could have bought for that money in the States. *Sigh*
In a big pot, boil the beef with leeks, garlic cloves, and onion halves, about 45 minutes.
While the meat cooks, add all the vegetables and seasonings into another pot and saute for a few minutes with 2 tbsp of chili oil. If you don’t have chili oil, saute the red chili pepper spices (gochujang and gochugaru) with vegetable oil to make chili oil.
After removing the beef, strain the broth and add to the sauteed mixture. Add more water if necessary, covering at least an inch above the ingredients.
Once the beef is cool enough to handle, cut into long strips. If using brisket or skirt steak, the meat can be easily ripped by hand.
Boil everything together for 15~20 minutes . Adding a beaten egg is optional at this time.
TIme to eat!
“Leftovers” for the next day. Don’t hesitate to make extra as it keeps well refrigerated for a few days.
Up close and personal.
