How to make Seafood sinigang (sour and savoury seafood soup)

  1. Heat the olive oil in a 3-litre saucepan over medium heat until shimmering. Add the garlic and cook until light golden, then immediately remove the saucepan from the heat. Transfer the garlic mixture to a bowl and let it cool for 1 minute. Stir in the parsley and lemon zest, then set aside.

  2. Pour the seafood stock into the same saucepan used for the garlic. Add the lemon juice and sugar, then bring the mixture to a boil over medium heat. Add the onions and tomatoes, cover the pan, reduce the heat to low, and simmer for 5 minutes, or until the onions are translucent and the tomatoes are mushy.

  3. Place the fish in a strainer or colander and immerse it in the simmering broth. Cook for 3–5 minutes, until opaque throughout, being careful not to overcook. Transfer the fish to a plate and set aside.

  4. Add the beans to the strainer and immerse them in the simmering broth. Cook for about 5 minutes, or until tender but still vibrant green. Transfer the beans to a plate and set aside.

  5. Place the chiles and water spinach in the strainer and immerse them in the simmering broth. Cook for about 1 minute, or until tender but still vibrant in colour. Transfer the chiles and spinach to a plate and set aside.

  6. While the broth continues to simmer, taste and adjust the seasoning with fish sauce and more lemon juice as needed.

  7. Distribute and arrange the fish, shellfish, and vegetables into each of four bowls.

  8. Remove the broth from the heat and ladle it into the bowls with the seafood and vegetables. Sprinkle each serving with the gremolata. Serve the soup piping hot, accompanied by rice or crusty bread.
