Begin by preparing your Thai clear pork broth, simmering it gently for at least 30 minutes to extract maximum flavor. While the broth is cooking, prepare the Char Siu according to its recipe, ensuring it's marinated well to develop rich, savory sweetness. Once done, strain the broth to remove any solid ingredients, leaving a clear, fragrant liquid.

While the broth simmers, mince your scallions and set them aside. Cook the wontons according to the package instructions, usually around 5-7 minutes, until they float and become tender. Simultaneously, cook the thin wonton noodles in boiling water for about 3-4 minutes until al dente, then drain and rinse them under cold water. Blanch the mini bok choy for 1 minute in boiling water, then strain everything to prepare for assembly.

Once all your ingredients are prepped, return the strained broth to a pot and bring it to a gentle boil over medium heat. Stir occasionally to ensure it heats evenly and the flavors meld beautifully. This step is crucial for a comforting Char Siu Noodle Soup, so allow it to bubble lightly for about 5 minutes to intensify the flavors.

To serve, place a generous portion of wonton noodles in each bowl, followed by the cooked wontons and blanched bok choy. Carefully ladle the hot broth over the noodles and ingredients, ensuring everyone gets a taste of that aromatic liquid. Top each bowl with sliced Char Siu, a drizzle of garlic oil, minced scallions, and season with white pepper, chili vinegar, and a splash of fish sauce to suit your taste.
