Podi Idli is a spicy and flavorful variation of the traditional idli, where idlis are coated with a special spice powder called podi. The podi is made by roasting and grinding a mixture of lentils, spices, and dried red chilies. The cooked idlis are then tossed in the podi to give them a spicy and tangy flavor. Podi Idli is a popular street food in South India and is often served with coconut chutney and sambar.
