I was recently in Cambodia collecting data for my masters thesis research, as part of the Fish on Farms project: fishonfarms.landfood.ubc.ca. While in the Prey Veng province, a lovely Cambodian woman let me film her making traditional sour soup. Everyone makes their own special sour soup... she used beef, morning glory (a leafy green), and fish paste. She even gave me a bowl to try - it was delicious!
