- Soak urad dal in a separate bowl for the same duration.
2. Grinding the Batter
Once the rice and dal have soaked properly, it’s time to grind them into a smooth batter.
-
Drain the soaked ingredients: Rinse them slightly to remove any remaining starch.
-
Grinding: Use a wet stone grinder, blender, or food processor. Add the urad dal first and grind it to a fluffy consistency. Then add the soaked rice little by little and continue grinding.
-
Consistency Check: The batter should be smooth and thick, similar to pancake batter. Add water as necessary, but ensure it is not too runny.
3. Fermentation
Once ground, transfer the batter to a large bowl, leaving space for the batter to rise.
-
Cover: Use a clean kitchen cloth or lid to cover the bowl. Insulate it with a kitchen towel for warmth.
-
Let it Ferment: Place it in a warm area for a minimum of 6 to 12 hours, depending on your environment.
-
Check the Batter: The batter is ready when it has increased in volume and has a slightly sour aroma.
Cooking the Perfect Dosa
With your well-soaked and fermented batter ready, let’s discuss how to cook dosas.
Steps to Cook Dosas
-
Preheat your Pan: Use a cast-iron skillet or a non-stick pan and preheat it over medium flame.
-
Add Oil: Lightly grease the surface with oil using a paper towel.
-
Pour the Batter: Using a ladle, pour the batter onto the center of the pan and spread it in a circular motion to form a thin, even layer.
-
Cooking: Cook the dosa for about 2 to 3 minutes until the edges lift and turn golden brown. Drizzle a little oil around the edges.

What is dosa batter, and why is it soaked overnight?
Dosa batter is a fermented mixture made primarily from rice and black gram (urad dal) that’s used to make dosas, a popular South Indian crepe. Soaking the ingredients overnight before grinding is essential to achieve the right consistency and flavor. This process allows the grains and legumes to absorb water, facilitating easier grinding and promoting the fermentation process.
Soaking the batter for an extended duration also enhances the nutritional value. The fermentation that occurs overnight helps break down antinutrients, making the nutrients in the batter more available for absorption in the body. Additionally, the fermentation adds a unique tangy flavor to the dosas, which is a hallmark of authentic preparation.
How long should I soak the ingredients for dosa batter?
Typically, you should soak the rice and urad dal for at least 4 to 8 hours. However, many people prefer to soak the batter overnight for convenience and optimal fermentation. The exact soaking time can vary based on the temperature and humidity of your environment; warmer climates might require shorter soaking times, while cooler temperatures may need longer.
Soaking for the appropriate duration ensures that the grains soften sufficiently, which is crucial for achieving a smooth and lump-free batter after grinding. Always remember to adjust soaking times based on your specific conditions for the best results.
How do I know when the dosa batter is ready to use?
The dosa batter is considered ready when it has significantly increased in volume and has a light, airy texture. A good indication is the presence of bubbles on the surface, which shows that fermentation has occurred. The batter should also have a slightly tangy aroma, indicating that the natural fermentation process is at work.
If you are unsure, you can conduct a simple test by dropping a spoonful of the batter into a glass of water. If it floats, your batter is correctly fermented and ready to use. If it sinks, it may need more time to ferment.
Can I store leftover dosa batter, and if so, how?
Yes, you can store leftover dosa batter. If you have excess batter after making dosas, transfer it to an airtight container and refrigerate it. Properly stored, dosa batter can last up to a week in the refrigerator. If you notice any off smells or discoloration, it’s best to discard it.
When you’re ready to use the stored batter, remember to bring it to room temperature before preparing your dosas. You may need to stir it well and add some water to adjust the consistency if it thickens while in the refrigerator.
What should I do if my dosa batter is too thick or too watery?
If your dosa batter is too thick, you can easily remedy this by adding a little water. Gradually mix in water until you reach the desired consistency. It’s important to do this in small amounts to avoid making the batter too runny. A well-balanced batter should be pourable but not excessively thin.
Conversely, if your batter is too watery, you can thicken it by adding more ground rice or dal. Make sure to grind them into a fine powder before incorporating them into the batter to maintain a smooth texture. Keep testing the batter as you adjust to ensure it achieves the right consistency for perfect dosas.
Can I use a blender instead of a stone grinder for making dosa batter?
Yes, you can use a blender to make dosa batter. While traditional stone grinders are favored for their ability to produce a finer texture, modern blenders can do an excellent job as well. When using a blender, it’s helpful to soak the rice and dal separately and blend them in batches to ensure a smooth consistency.
Keep in mind that you may need to add water gradually while blending to prevent the mixture from becoming too thick. Additionally, blending in smaller portions will allow for better control over the texture, making it easier to achieve the perfect dosa batter even without a traditional stone grinder.
