Bánh Canh Giò Heo is a Vietnamese noodle soup dish made out of thick rice noodles with collagen rich pork soup made out of pork hocks. "Bánh Canh" is a Vietnamese word meaning "soup cake", "Giò Heo" on the other hand means "pork leg". Now you might be wondering why of all parts you want to use the leg? Well this might surprise you but this is one of most flavourful cut of a pork and it contains a lot of collagen which naturally makes the soup thick.
