Pho is a traditional Vietnamese noodle soup known for its aromatic and rich flavors. The key ingredients are:
- **Rice Noodles**: Soft, flat rice noodles that serve as the base of the dish, providing a smooth and chewy texture.
- **Beef Broth**: A fragrant and savory broth made from simmering beef bones, spices (such as star anise, cinnamon, and cloves), and aromatics for hours to develop a deep, complex flavor.
- **Sliced Beef**: Thinly sliced raw beef, typically served on the side, which cooks gently in the hot broth when added to the soup, ensuring tenderness and a fresh flavor.
- **Red Onions**: Thinly sliced red onions add a sharp, slightly sweet taste and a bit of crunch.
- **Green Onions**: Chopped green onions provide a mild, pungent flavor and fresh crunch.
- **Cilantro**: Fresh cilantro leaves add a burst of herbal freshness and a hint of citrus, enhancing the overall flavor profile.
This combination creates a harmonious and aromatic soup that is both comforting and refreshing, with a perfect balance of textures and flavors. The addition of raw beef that cooks in the hot broth adds a dynamic and interactive element to the dining experience.
