It's a Peruvian large dried corn kernel,called Cancha or Peruvian style corn nuts.When toasted kernels pops on the inside only and leaves the outer shell intact, gives Cancha quite a unique texture. Cancha is great as a snack food in Peru. Heat the oil in a heavy-bottomed skillet over medium flame. Add the cancha and toss to coat with the oil. Cover the pan, shaking the pan from time. The kernels will begin popping and will take on a golden brown color until popping subsides (10 min.) Drain on a plate lined with paper towels. Season with salt and ground red chile pepper and sugar.
