If your idli batter is too runny, add 1-2 tablespoons of rice flour or semolina (rava) to thicken it. Mix well and let it rest for 15-20 minutes before steaming.
Detailed Explanation:
A runny idli batter will result in flat, dense idlis instead of the soft, fluffy ones we desire. The consistency of the batter is crucial for proper fermentation and steaming. Here's a step-by-step guide to fixing runny idli batter:
- Assess the Batter: First, determine how runny the batter is. A slightly runny batter might only need a small adjustment.
- Add Rice Flour or Semolina: Start by adding 1 tablespoon of rice flour or fine semolina (rava) to the batter. These ingredients absorb excess moisture and help thicken the mixture. Rice flour will give a slightly smoother texture, while semolina can add a bit of a grainy texture.
- Mix Thoroughly: Gently fold the rice flour or semolina into the batter until it's fully incorporated. Avoid overmixing, as this can develop the gluten and make the idlis tough.
- Let it Rest: Allow the batter to rest for 15-20 minutes. This gives the rice flour or semolina time to absorb the excess liquid and thicken the batter.
- Check the Consistency: After resting, check the consistency of the batter. It should be thick enough to coat the back of a spoon and slowly drip off. If it's still too runny, add another half tablespoon of rice flour or semolina, mix, and let it rest again.
- Steam a Test Idli: Before steaming the entire batch, steam a single idli to test the consistency. This will help you determine if the batter is now the correct consistency.
- Adjust as Needed: If the test idli is still not fluffy, you may need to add a tiny amount of baking soda (a pinch) to help with the rise. Be careful not to add too much, as it can affect the taste.
Pro Tip:
Avoid adding water to the batter after fermentation. If you find the batter is too thick after fermentation, add a small amount of *unfermented* batter (reserved before fermentation) or a tiny splash of milk instead of water to adjust the consistency. This helps maintain the proper balance of microorganisms for optimal idli texture.
