Ingredients
How to Make It
Rinse the urad dal thoroughly under running water until the water runs clear. Soak it in enough water for at least 4 hours or overnight.
In a separate bowl, rinse the idli rava once or twice, then soak it in enough water for 4 hours. After soaking, drain the idli rava well and squeeze out excess water using your hands. Set aside.
Drain the soaked urad dal, reserving the soaking water. In a blender, combine the drained urad dal, squeezed idli rava, and cooked rice. Add about 2-3 tablespoons of the reserved water and grind to a smooth paste.
Gradually add more water, a tablespoon at a time, and continue grinding until the batter is smooth, fluffy, and of pouring consistency. The batter should be thick but able to coat the back of a spoon.
Transfer the batter to a large bowl. Add salt and mix well with your hand or a spoon. Cover and let it ferment in a warm place for 8-10 hours or overnight.
Once fermented, the batter will rise and have a pleasant sour aroma. Gently stir the batter once.
Grease the idli moulds with oil. Pour the batter into the moulds, filling them about 3/4 full.
Steam the idlis in a steamer, electric cooker, or pressure cooker (without the whistle) for 10-12 minutes, or until a toothpick inserted comes out clean.
Let the idlis cool for a minute, then demould using a spoon. Serve hot with coconut chutney and sambar.

Health Benefits
Leftover Rice Idli is a fermented food, which means it contains beneficial probiotics that support gut health. The fermentation process also enhances the bioavailability of nutrients, making it easier for your body to absorb vitamins and minerals. Urad dal adds plant-based protein and fibre, while rice provides energy. These idlis are steamed, not fried, making them a low-fat, heart-friendly choice. They are naturally gluten-free and easy to digest, suitable for all ages.
Pro Tips
- →Use freshly cooked rice that has cooled completely; hot rice can make the batter sticky.
- →The consistency of the batter is crucial: it should be thick but pourable. Adjust water accordingly.
- →Fermentation time depends on the climate. In colder weather, place the batter in a warm spot or use a preheated oven (turned off) to speed up fermentation.
- →If the batter hasn't fermented well, you can add a pinch of baking soda before steaming for fluffier idlis.
- →Grease the idli moulds well to ensure easy removal.
Variations
- 1Add 1/4 cup of grated carrots or chopped coriander leaves to the batter for extra color and flavor.
- 2For a protein boost, add 1/4 cup of cooked quinoa or oats to the batter.
- 3Replace idli rava with 1 cup of semolina (sooji) for a different texture; adjust water accordingly.
- 4For a tangier flavor, add 1/4 cup of yogurt to the batter before fermentation.
