Aehobak-guk (애호박국, Korean Zucchini Soup)
A clean summer soup of Korean zucchini and salted shrimp, built on quick anchovy-kelp broth and finished before the half-moons lose their shape on a weeknight table.

Created by
A batch pot of spicy shredded beef soup, built on patient broth, hand-torn brisket, fernbrake, and long scallions, with chili oil bloomed gently so the soup tastes deep instead of harsh.
Yukgaejang lives or dies in your hands, not in the chili. The beef is boiled until it gives way, then torn with your fingers into long strands. My teacher, Master Seong-nyeo, would tap the board if a student reached for a knife. Cubes make a stew. Strands make yukgaejang.
This is a pot for a cold day, or for a house that needs feeding twice. It looks fierce because the broth runs red, but it should not taste like raw chili. You bloom gochugaru (Korean chili flakes) gently in oil, season the beef and fernbrake before they meet the broth, and use more scallion than a shy cook thinks proper. The scallion sweetens and softens. The gosari (fernbrake) gives chew. Bean sprouts go late so they keep their snap.
I won't tell you this is quick. The work is boiling, cooling, tearing, and waiting while the broth takes the seasoning. A pressure cooker may shorten the boiling, and prepared gosari may save you a night of soaking. Those are honest changes. The tearing is not optional, and neither is tasting the salt at the end. 손맛 is real; I measure it anyway.
The name yukgaejang keeps an older word inside it: gaejang, a spicy dog-meat soup associated with sambok, the three hottest days of summer, and described in the 1849 seasonal record Dongguk Sesigi. As beef versions spread in the late Joseon and modern periods, the dish became a red beef soup for homes and restaurants, especially suited to tough cuts boiled until they could be pulled apart. Daegu's red beef soups and ttaro-gukbap show how this strengthening soup moved from seasonal eating into everyday public food.

Put the brisket or shank in a large bowl and cover it with cold water for 20 minutes, changing the water once if it turns very red. Drain and rinse the beef. This is not washing away flavor; it keeps the broth clean enough that the chili oil will taste clear later, not muddy.
Put the beef in a 6 to 8 quart pot with 14 cups cold water, the halved onion, smashed garlic, ginger, and peppercorns. Bring it to a boil over medium-high heat, skim the gray foam for the first 10 minutes, then lower the heat to a steady simmer. Cover with the lid slightly ajar and cook 1 hour 45 minutes to 2 hours 15 minutes, until a chopstick slides into the thickest part easily and the meat begins to separate along its grain.
Lift the beef onto a tray and strain the broth through a fine strainer. Discard the onion, garlic, ginger, and peppercorns. Skim off heavy fat, but leave a few droplets because a completely stripped broth tastes thin. Measure 10 cups broth for the soup. If you have less, add water. If you have much more, boil it down until it reaches 10 cups. The measure matters because the salt and chili are written for that amount.
While the beef cools, cut the prepared gosari into 3-inch lengths, cut the scallions the same length and split any thick white parts lengthwise, tear the oyster mushrooms into strips, and rinse the mung bean sprouts. If vacuum-packed gosari smells sharp or tastes bitter, boil it in plain water for 5 minutes, rinse, and squeeze it dry before using. Fernbrake should be chewy and earthy, not harsh.
When the beef is cool enough to handle, tear it by hand along the grain into long strands about 1/4 inch thick and 2 to 3 inches long. Discard hard gristle. Do not cube the beef. Cubes sit in the broth like stew meat; strands catch the seasoning and become part of the soup itself. My teacher, Master Seong-nyeo, would tap the board if a student reached for a knife here.
Wipe the soup pot clean and set it over low heat. Add the neutral oil and 2 tablespoons sesame oil, then stir in the gochugaru for 30 to 45 seconds, just until the oil turns a clear brick red and glossy. Pull the pot off the heat if the chili darkens. This is chili oil, not fried chili, and burnt gochugaru turns the whole pot bitter.
Add the torn beef, gosari, oyster mushrooms, and scallions to the chili oil. Add the guk-ganjang, minced garlic, salt, and black pepper, then toss everything over medium heat for 2 to 3 minutes until the strands are evenly red and the scallions begin to soften. Seasoning the solids first gives you a soup with depth. If you pour chili into broth and hope, you get red water.
Pour in the measured 10 cups beef broth and scrape the bottom of the pot clean. Bring it to a boil, then lower to a lively simmer and cook uncovered for 25 minutes. The scallions should collapse into the broth, the fernbrake should soften without losing its chew, and the red oil should bead across the surface.
Add the mung bean sprouts and keep the lid off from this point. Simmer 8 minutes, until the sprouts are cooked but still have a clean bite. Taste the broth. If it tastes flat, add the optional fish sauce. If it only needs salt, add fine sea salt 1/4 teaspoon at a time. Soup soy sauce varies from bottle to bottle, so this last tasting is not a decoration. It is the cook's work.
If using eggs, drizzle the beaten eggs in a thin circle over the simmering soup, wait 20 seconds, then stir once so they set in soft ribbons. Turn off the heat and rest the soup 10 minutes before serving; yukgaejang tastes better when the broth has stopped shouting and started settling. Finish with 1 teaspoon sesame oil if the pot needs roundness. Serve with hot rice and kimchi.
