Close to hitting 70, Bhagyalakshmi Ammal has been virtually defying the very looks of idli—and yet adding fame to the traditional Indian rice-cake that enjoys a legacy of two centuries in her part of the country. In the otherwise nondescript village of Ramasseri in Kerala, the woman steams the batter in clay containers kept on mud-raised stoves that use tamarind-tree logs as firewood. And what Ammal pulls out from the vessel in her smoky kitchen is amusing: the fluffy eatable is circular, but not saucer-shaped like the typical idlis. They look like a flat and edited cousin of thick dosas.
