The main ingredient in traditional pho is rice noodles, known as "bánh phở." Pho is a quintessential Vietnamese dish that consists of a flavorful broth, typically made from simmering meat (usually beef or chicken), herbs, and spices. The rice noodles serve as the base of the dish, providing a chewy texture that complements the richly flavored broth. Pho is often garnished with fresh herbs, bean sprouts, lime, and chili, allowing diners to customize their experience and adding layers of flavor to this beloved soup.
