Japan (Nara Prefecture as primary living tradition; Buddhist temple morning food culture, documented since Nara period 710–794 CE)
Chagayu (茶粥 — tea porridge) is one of Japan's oldest breakfast preparations, surviving as a living culinary tradition primarily in Nara Prefecture (and to a lesser degree in Wakayama and Osaka) where it forms the morning meal of Buddhist temples, farming households, and tea-growing communities. The preparation is disarmingly simple: hōjicha (roasted green tea) or green bancha brewed strongly, then used as the cooking liquid for white rice cooked to a loose, watery consistency — the opposite of the dense porridge (kayu) made with plain water. The resulting chagayu has a distinctive roasted-grain, barely-savoury flavour from the tea, with the texture of loosely cooked gruel. Toppings are minimal: pickled plum (umeboshi), sesame seeds, natto, or small amounts of tsukemono. The tradition's origin is monastic: Buddhist temples in Nara's Yamato region prepared chagayu from lower-grade tea as a frugal morning meal aligned with shojin ryori principles. Hōryū-ji Temple's chagayu and the Kasugataisha shrine's ceremonial chagayu service are the most historically documented. The dish is entirely alien to Western porridge concepts: it is designed to be liquid, not thick; it is designed to be drunk as much as eaten; and the tea flavour is primary, the rice secondary.

{"Tea-to-rice ratio: 1 litre strongly brewed hōjicha (or strong bancha) to 100g dry rice produces the standard loose consistency; increase rice to 150g for thicker preference","Cooking protocol: bring the tea to the boil, add rinsed rice, simmer covered on very low heat for 30–40 minutes until grains are fully expanded and beginning to dissolve at the edges","Texture target: chagayu should be more liquid than solid; when you pour it from the pot, it should flow freely but with visible intact rice grains — looser than congee, more substantial than broth","Tea selection: hōjicha produces a warm, nutty chagayu; matcha produces a visually striking green chagayu used in Uji and Kyoto tea-ceremony hospitality; bancha produces a lighter, more delicate character","Serving temperature: chagayu is served very hot (75–80°C) and should be eaten slowly — the liquid cools as it's consumed; the final spoonfuls are a different temperature experience from the first"}
{"Nara chagayu experience: the Yoshinoyama area's inns and temples serve chagayu as a genuine living tradition for breakfast — combining with a visit to the cedar forests of Yoshino creates an immersive experience of Nara's culinary-natural heritage","Matcha chagayu upgrade: whisk 1 tsp ceremonial matcha into the broth just before serving — the matcha adds umami depth and a vivid green colour appropriate for tea ceremony hospitality contexts","Rice overnight in cold tea: cold-steep cooked rice in cold hōjicha overnight; serve cold in summer — a completely different expression of the chagayu concept as a refreshing summer breakfast"}
{"Making chagayu too thick — the defining characteristic is its flowing, liquid quality; thick porridge is kayu, not chagayu","Using low-quality bancha tea — the tea is the primary flavour; a tea too bland produces insipid chagayu; use strongly brewed good-quality hōjicha","Adding complex toppings — chagayu's simplicity is the point; elaborate toppings appropriate for okayu (plain rice porridge) are wrong for the meditative simplicity of chagayu"}
