- 1
Soak 20g of dried seaweed in cold water for 15 minutes until it expands, then drain well and cut into bite-sized strips.
- 2
In a heavy-bottomed pot over medium heat, add 1 tsp sesame oil and sear 600g beef brisket until browned on all sides.
- 3
Add the soaked seaweed to the pot and stir-fry with the beef for 3 minutes until the seaweed turns a vibrant, glossy green.
- 4
Pour in 1.5 liters of water and bring the mixture to a gentle boil over high heat, skimming any foam that rises to the surface.
- 5
Once boiling, reduce heat to low and add 4 minced garlic cloves and 2 tbsp soup soy sauce to build the flavor base.
- 6
Cover partially and simmer for 30 minutes; the broth should turn a milky, pale green color as the seaweed releases its essence.
- 7
Stir in 300g sliced radish and cook for another 10 minutes until the radish is tender and translucent.
- 8
Taste the broth and add 1 tsp salt if needed; finish by adding 3 chopped green onions just before removing from the heat.
