If the Medu Vada batter becomes too runny, add rice flour in it to make it smooth. There is a timing of adding salt to the batter. Always, add it while grinding the dal as adding it afterwards can make the batter runny. You can also use the Medu Vada machine to drop it in the hot oil.
The Medu Vada Recipe is a very traditional South Indian Tiffin/ Breakfast dish that is made from whole urad dal. Each home has a special recipe of how they spice up the Medu Vada batter. In this recipe, I have spiced and flavored the batter with ginger and green chillies.
Add salt, peppercorn, onions, cilantro, curry leaves, ginger, and green chilies right before frying the medu vada to avoid runny batter. Add a couple of tablespoons of sooji or rice flour if your batter is runny. Deep fry your vadas on medium heat for best results. Make sure to use very little ice-cold water to grind the batter.
These urad dal vada are also known as Garelu in Andhra, Uzhunnu Vada in Kerala, Uddina Vada in Kannada and Medhu Vadai, Ulundu Vadai in Tamil. Rinse urad dal a couple of times in fresh water. Then soak the lentils for 4 hours or overnight. Grind or blend the soaked lentils to a smooth batter with water.
