10 Tips to Make the Perfect Dosa/Idli Batter

Dosas and idlis are beloved staples of South Indian cuisine, cherished for their light, fluffy texture and delicious flavor. The foundation of these dishes lies in the batter, which, when prepared correctly, results in perfect dosas and idlis. Creating the ideal batter involves a combination of selecting the right ingredients, mastering the fermentation process, and using specific techniques. Here are 10 detailed tips to help you make the perfect dosa/idli batter at home.

1. Choose the Right Rice and Lentils

The foundation of good dosa/idli batter is selecting the right type of rice and lentils. Traditionally, parboiled rice (idli rice) is preferred for its ability to yield a soft and fluffy texture. You can also use a combination of regular rice (such as sona masuri) and parboiled rice. For lentils, urad dal (split black gram) is essential. It provides the necessary fermentation properties and contributes to the batter’s volume and texture.

Tip: Use a ratio of 3:1 for rice to urad dal for idli batter and 4:1 for dosa batter. You can also add a tablespoon of fenugreek seeds to the lentils for better fermentation and flavor.

2. Proper Washing and Soaking

Thoroughly washing the rice and lentils removes excess starch and helps in better fermentation. Rinse them multiple times until the water runs clear. Soaking is another crucial step. Soak the rice and urad dal separately for at least 6-8 hours or overnight. This softens the grains and dal, making them easier to grind and aiding in better fermentation.

Tip: Soak the fenugreek seeds with the urad dal to enhance the batter’s flavor and fermentation.

3. Use the Right Equipment for Grinding

A wet grinder is the preferred equipment for grinding dosa/idli batter as it produces a smoother consistency and retains the batter’s temperature, which is crucial for fermentation. If you don’t have a wet grinder, a high-quality blender can also work, though you may need to grind the ingredients in batches and with extra care.

Tip: Add water gradually while grinding. For urad dal, use ice-cold water to maintain the batter’s temperature and prevent overheating.

4. Grinding Techniques

Grind the urad dal first until it becomes fluffy and smooth. The batter should be light and airy, which is crucial for the fermentation process. Transfer it to a large bowl. Next, grind the rice to a slightly coarse consistency. The rice batter should have a bit of texture, which helps in creating the crispy edges in dosas and the porous texture in idlis.

Tip: The total grinding time for urad dal should be around 20-25 minutes and for rice about 25-30 minutes. Ensure the consistency of the batter is neither too thick nor too runny.

5. Mixing the Batter

Once both the rice and urad dal are ground, mix them together thoroughly in a large bowl. Use your hand to mix as the warmth of your hand can help kickstart the fermentation process. The consistency should be pourable but not watery.

Tip: Add salt after fermentation, as salt can slow down the fermentation process. However, in hot climates, you can add salt before fermentation to avoid over-fermentation.

6. Fermentation Process

Fermentation is the key to achieving the right texture and taste in dosa and idli batter. The ideal fermentation environment is warm and humid. In cooler climates, you might need to use an oven with the light on or a warm spot in your kitchen to aid the process. Fermentation time can vary from 8-24 hours depending on the climate.

Tip: To check if the batter is fermented, it should have doubled in volume, and you should see air pockets on the surface. It should also have a slightly sour aroma.

7. Maintaining Consistency

After fermentation, the batter will rise and become airy. Gently mix the batter to ensure uniformity before using it. For idlis, the batter should be thick yet pourable. For dosas, you might need to dilute the batter slightly to achieve a spreadable consistency.

Tip: Use water sparingly when adjusting the consistency post-fermentation. Always add little by little and check the consistency.

8. Storage and Shelf Life

Once fermented, store the batter in the refrigerator to prevent over-fermentation. The batter can last up to a week when stored properly. If you plan to store it for longer, you can freeze portions of the batter in airtight containers.

Tip: Before using refrigerated batter, let it come to room temperature and stir well. If the batter appears too thick, add a little water to adjust the consistency.

9. Making Perfect Idlis

To make perfect idlis, grease the idli molds with a little oil and pour the batter into each mold. Steam them in an idli steamer or pressure cooker (without the whistle) for about 10-12 minutes. The idlis should rise and become fluffy. Check by inserting a toothpick; if it comes out clean, the idlis are ready.

Tip: Allow the idlis to cool for a few minutes before removing them from the molds to prevent them from sticking.

10. Making Crispy Dosas

For dosas, heat a non-stick or cast-iron tawa (griddle) on medium heat. Pour a ladleful of batter onto the center and spread it in a circular motion to form a thin layer. Drizzle a little oil around the edges and cook until the dosa turns golden brown and crispy. Fold and serve hot.

Tip: Ensure the tawa is well-seasoned and hot enough before pouring the batter. If the tawa is too hot, the batter will not spread evenly. You can sprinkle a little water on the tawa to bring down the temperature slightly before spreading the batter.

Bonus Tips for Enhancing Your Dosa/Idli Batter

  1. Adding Poha (Flattened Rice): Soaking a small amount of poha with the rice can help in achieving softer idlis and crispier dosas.
  2. Using Cooked Rice: Adding a handful of cooked rice while grinding can contribute to a softer texture.
  3. Incorporating Quinoa or Millet: For a healthier twist, replace a portion of the rice with quinoa or millet.
  4. Experimenting with Lentils: Along with urad dal, you can add a small quantity of moong dal or toor dal for a different flavor profile.
  5. Ensuring Proper Cleaning: Clean your grinder thoroughly after each use to prevent any leftover batter from affecting the next batch.


Making the perfect dosa/idli batter is an art that combines the right ingredients, techniques, and a bit of patience. By following these detailed tips, you can create a batter that results in soft, fluffy idlis and crisp, delicious dosas every time. Whether you’re a novice or an experienced cook, mastering the dosa/idli batter will bring the authentic flavors of South Indian cuisine to your kitchen. Enjoy the process and relish the delightful outcomes of your culinary efforts!
