Seppankizhangu Roast, also known as Yam Roast, is a delicious South Indian dish featuring crispy, spiced yam slices. To prepare, peel and cut seppankizhangu (elephant foot yam) into thin rounds or cubes. Boil the pieces until partially cooked, then drain and let them cool. In a bowl, mix rice flour, chili powder, turmeric powder, salt, and a little oil to create a spice coating. Toss the yam pieces in this mixture until well coated. Spread them on a baking tray or pan and roast them in the oven or on a stovetop until golden brown and crispy. Serve hot as a tasty snack or side dish with rice and sambar!
