Cut the white part of the green onions, then finely chop it. Next, finely chop the cilantro. Set both aside for later use as garnish.
Dice the shrimp, then give it a quick chop to break them down further.
In a large mixing bowl, combine the ground pork and shrimp. Add the minced shallots, along with the chopped green onions and cilantro. Mix everything thoroughly until the ingredients are evenly distributed.
Season the pork and shrimp mixture with salt, MSG (or chicken bouillon powder), ground black pepper, and one tablespoon of oyster sauce. Stir everything together, making sure the seasoning is well incorporated into the filling.
Add one teaspoon of cooking oil to the mixture to help keep it moist and tender. Continue mixing. Let the mixture marinate for about 30 minutes.
Take one wonton wrapper and place it flat in your palm. Scoop a modest amount of the pork and shrimp filling and place it in the centre of the wrapper. Carefully fold and wrap the wonton, ensuring the edges are sealed properly. Repeat this process for the remaining wonton wrappers.
In a pot, bring the prepared chicken stock to a rolling boil over high heat. Lightly season the broth with salt and mushroom powder, tasting as you go to ensure the flavour is balanced and suits your preference.
In a separate pot, bring a generous amount of water to a rolling boil. This pot will be used to cook the wontons separately to keep the broth clear and flavourful.
Gently add the wontons to the pot of boiling water. Cook for about 1 minute, ensuring the wrappers are tender but still hold their shape. Avoid overcooking.
Once the wontons are cooked, carefully remove them from the boiling water. Place the wontons directly into individual serving bowls.
For garnish, sprinkle the freshly chopped green onions over the wontons. Optionally, top with a few pieces of crispy pork greaves for extra crunch and depth of flavour.
Finally, pour the hot chicken broth over the wontons in each bowl. Your Wonton Soup is now ready to serve! Enjoy it hot while the flavours are fresh and vibrant.
