The smooth, flowing mixture is poured over hot rice and finished with green onion and nori. Adding the cool broth in several small portions and fully incorporating each one prevents lumps and preserves the yam's characteristic stretch. Mariko was the twentieth station of the fifty-three Tokaido post towns, and travelers sought its tororo-jiru as sustaining food. Jinenjo is harvested from mid-autumn into winter, and some communities eat the dish on January second while wishing for health through the year.
