In its simplest form, zhou, also known as congee or rice porridge, is watered-down rice. It’s poor people’s food, what you make to stretch out the rice when there isn’t enough to feed. It is humble, homely, yet there’s something transformative about it. Hours of gentle simmering tenderize the food, and the nutrients give themselves to the broth, ready to be absorbed and digested, soothing stomachs and souls alike.
