Podi Idli is a popular South Indian dish made with idlis (steamed rice cakes) coated in a flavorful spice powder called podi. The podi is made with roasted lentils, spices, and dried red chilies, which are ground into a coarse powder. The idlis are then tossed in the podi, giving them a delicious and aromatic coating. Podi idli is a great way to use leftover idlis and can be enjoyed as a breakfast or snack.
