what kind of noodles are in pho

The noodles used in pho are called "banh pho" noodles. They are flat rice noodles made from rice flour, typically white and varying in width from very thin to wider strips. Banh pho noodles have a distinctive square or rectangular cross-section, unlike most other rice noodles that tend to be round. When cooked, these noodles become soft, slightly chewy, and somewhat translucent. They are essential to the dish and give pho its characteristic texture and appearance.
