Okaisan

Okaisan is a savory rice porridge simmered in roasted bancha or hojicha tea, affectionately named by people across Wakayama Prefecture. The rice turns soft and plump, its sweetness mingling with the tea's gentle bitterness for a smooth, easy-to-swallow texture. Sweet potato or taro is often stirred in to make the bowl more filling during busy seasons, and some households add broad beans or snow peas for a version called "bean chagayu." A single pinch of salt is usually all the seasoning it needs.

Bancha tea leaves are steeped in a cloth bag in boiling water until the liquid turns a deep color, then the bag is removed. Washed rice is added and cooked over high heat, stirred from the bottom with a wooden ladle as it simmers. Once the grains swell and soften, the heat is turned off and a pinch of salt added to taste. Households vary the brewing and the fillings — a plain version called "bozu chagayu" contains nothing extra, while others fold in mochi, dumplings, or seasonal vegetables.

Wakayama's mountainous terrain, sometimes called the "land of trees," left little flat ground for growing rice, so rice was reportedly a precious commodity for many households. Simmering a small amount of rice into a large pot of porridge was one way to stretch it further and fill the stomach. In the sparsely arable south, chagayu is said to have served as a daily staple eaten several times a day, and a local folk song from the Inami area recalls siblings squabbling over servings with sweet potato inside. The practice of extending scarce rice still shapes the dish eaten today.
