Origin
Japan — okayu documented since Nara period; zosui developed as hot pot culture formalized in Edo period
Description
Japanese rice porridge encompasses two distinct preparations with different rationale: okayu (お粥, rice porridge) is plain rice cooked slowly with large water ratio (5-10:1 water:rice) until completely soft and creamy — a recovery food, sick-day meal, and infant food. Zosui (雑炊, miscellaneous cook) is the hot pot shime (finishing) preparation — leftover nabe broth with rice added, cooked briefly until rice has absorbed the enriched broth. The result is richer and more complex than okayu because of the accumulated broth. Both require specific rice: Japanese short-grain for the starch release that creates the characteristic creamy binding.

Okayu: pure gentle starch comfort; zosui: concentrated nabe broth absorbed into rice — umami-rich closing experience
