Rice porridge is an ancient preparation found across East and Southeast Asia, documented in Chinese records from the Zhou dynasty and as a daily staple in Cambodia known as Borbor. Its simple, nourishing nature has made it a shared comfort food throughout the region without a single contested origin.
