Lien explained that the broth sets this pho apart. While it retains the traditional pho broth made from beef bones with spices like star anise, cinnamon, and cardamom, additional ingredients such as tomatoes, lemongrass, and chili create a tangy and spicy flavor, with clams adding sweetness. These elements help mask the seafood aroma from the lobster and squid.
The garnishes also contribute to the flavor of the dish. In addition to the cilantro and scallions found in regular pho, dill is also used, a common herb in seafood soups. The broth has a reddish hue, resembling tom yum soup.
