Seven Tips And Tricks To Ferment Dosa Batter Perfectly
Ingredients Required
To make dosa batter, you’ll need rice and lentils (typically urad dal). Maintaining the right rice-to-lentil ratio is important for a good ferment. Use either a 3:1 or 4:1 ratio, with rice being the larger portion. Adding a small number of fenugreek seeds can also enhance fermentation and add to the dosa’s flavour and texture.
Correct Soaking Time
Soaking the ingredients is a crucial first step. Soak rice and lentils separately, as each ingredient requires a different amount of time. Rice should soak for about 4 to 6 hours, while lentils generally need 2 to 4 hours. This soaking time helps soften the grains, which will make the batter smoother when ground.

Grind In The Right Way
After soaking, grind the rice and lentils separately. Grind the lentils until they are smooth and fluffy, using only a little water. Then, grind the rice to a fine or slightly coarse consistency, depending on your preference. Using minimal water when grinding can give the batter a thicker consistency, which is ideal for fermentation. The act of grinding releases starch from the rice, which further aids in the fermentation process.
Mix Well
Once both the rice and lentil batters are ready, mix them in a large bowl. You can use your hands to mix, as this can naturally introduce beneficial microorganisms that can enhance fermentation. Ensure the batter is well-blended, but avoid over-mixing. Mixing with your hands for just a few minutes helps the batter gain air, which improves the fermentation.

Select The Right Consistency
The batter consistency is crucial for a good dosa. It should be slightly thick but still pourable. A helpful test is to see if the batter coats the back of a spoon; it should be neither too thick nor too thin. If the batter is too thick, add a small amount of water, but if it’s too thin, you can add a bit of rice flour to adjust it.
Cover It With A Perfect Cloth Or A Lid
To ferment the batter, cover it with a light cloth or lid. Avoid a heavy or airtight cover, as some airflow is essential for fermentation. The cloth or loose lid allows air to circulate, helping the batter to rise and become slightly sour, giving the dosa a balanced flavour.
Required Temperature
The right temperature is critical in the fermentation process. A warm environment is best, ideally around 30°C (86°F), as fermentation thrives in warm conditions. Leave the batter in a warm place for 8 to 12 hours. In colder climates, you can use the oven: turn it on for a few minutes, then switch it off, and leave the batter inside with the light on to create a warm environment.

The container you use should allow room for the batter to expand as it ferments. If your kitchen is especially cool, placing the container near a warm appliance, like a microwave or stove, can speed up the fermentation. You’ll know the fermentation is successful when the batter doubles in size and has a slightly tangy aroma.
Mastering dosa batter fermentation takes some patience and the right conditions, but the results are worth it. With the right ingredients, proper soaking, grinding, and a warm environment, you’ll have a well-fermented batter that makes delicious, crispy dosas.
