Oal — elephant-foot yam (suran/jimikand) — holds an almost proverbial place in Mithila: a local saying names three essential Maithil foods as kadali (raw plantain), kabkab (oal/yam) and meen (fish). The starchy tuber is peeled, boiled to tame its characteristic itch, and either cooked into a tarkari — a dry stir-fry or a tangy mustard-and-curd gravy spiced with garlic and chilli — or pounded into oal ki chutney, a thick, pungent dip brightened with mustard oil, garlic and lemon that keeps for days in winter.
Both forms are deeply home-style and seasonal, leaning on the cuisine’s signature mustard oil and garlic. Yam also appears as a bajka (fritter), but it is the curry and the fierce chutney that anchor it in the Maithil repertoire as a beloved cold-weather vegetable.
