Mussel Soup, or Honghap Tang, is a traditional Korean soup that embodies the essence of the sea and the harmonious blend of Asian flavors. Drawing from South Korea’s rich coastal heritage, this dish is revered for its simplicity and nourishment. Mussels, known as ‘honghap’ in Korean, are the star of this comforting soup, often consumed for its health benefits and savory flavor profile. Steeped in a light yet flavorful broth, it evokes the serene experience of the Korean coastline where fresh seafood is abundant. It’s a staple in Korean cuisine, especially enjoyed in the colder months.
Ingredients
- Fresh mussels – 2 pounds / 900 g
- Water – 6 cups / 1.4 liters
- Korean radish (mu) – 1 cup / 150 g, sliced thinly
- Dried kelp (dashima) – 2 pieces, 5 inches each
- Korean red pepper flakes (gochugaru) – 1 teaspoon
- Garlic cloves – 3, minced
- Green onions – 2, sliced
- Soy sauce – 2 tablespoons
- Salt – to taste
Instructions
- Thoroughly clean the mussels under cold running water. Remove any beards by pulling them down towards the hinge of the shell. Discard any mussels that remain open after tapping them gently.
- In a large pot, combine the water and dried kelp pieces. Bring to a gentle simmer over medium heat, allowing the kelp to flavor the water. After 15 minutes, remove the kelp.
- Add sliced Korean radish and minced garlic to the pot. Simmer for another 10 minutes until the radish is tender.
- Introduce the cleaned mussels, soy sauce, and red pepper flakes to the pot. Cover and boil on medium-high heat until mussels open, about 5 to 7 minutes.
- Season the soup with salt according to preference. Add green onions and cook for an additional minute.
- Ladle the soup into bowls, ensuring an even distribution of mussels and broth. Serve immediately.
