Pho is a traditional Vietnamese soup consisting of broth, rice noodles, herbs, and meat, typically either beef (pho bò) or chicken (pho gà). The broth is usually made by simmering bones, meat, and various spices like star anise, cinnamon, and cloves, often for several hours to develop a rich, complex flavor. Pho is often served with a plate of fresh herbs, such as basil, cilantro, and mint, alongside lime wedges, bean sprouts, and chili peppers, allowing for customization according to personal taste. This dish is a staple of Vietnamese cuisine and is enjoyed both as street food and in restaurants worldwide.
