Soak the seaweed. Rinse the dried miyeok briefly, then soak in cool water for 10–15 minutes until it’s soft and expanded. Drain well and cut into bite-size pieces.
Season the beef. Toss beef with 1 teaspoon sesame oil and 1 teaspoon soy sauce.
This adds flavor from the start.
Stir-fry for aroma. In a pot, heat 1 tablespoon sesame oil over medium. Add beef and cook until no longer pink. Add the drained seaweed and garlic, and stir-fry 2–3 minutes until glossy and fragrant.
Add water and simmer. Pour in 4 cups water (and a small piece of dried kelp if using).
Bring to a boil, then simmer 15–20 minutes. Remove kelp after 10 minutes to avoid bitterness.
Season to taste. Add soy sauce 1 teaspoon at a time, then adjust with salt. If you like, add a splash of fish sauce for extra umami.
The broth should taste clean, savory, and slightly briny.
Adjust consistency. If it’s too strong or crowded with seaweed, add more water. Simmer 5 more minutes to meld flavors.
Serve hot. Ladle into bowls. A drizzle of sesame oil on top is optional but lovely.
