Vadai is one of the popular traditional south Indian snacks made using Urad Dhal (Ulundhu). perfectly crispy outside, soft and fluffy inside – defines a perfect vadai. It’s also served as an appetizer. Vadai occupies a special place in breakfast combo and special occasion meals. It is also prepared during festivals for neivedyam. Typically, it is served with idli and pongal. the idli vada / pongal vada combination with chutney and sambar is the popular breakfast in many households. Many people make medhu Vada with a piece of banana leaf or a polythene cover, for making shape of Vada. But in hotel/restaurants, without using anything, just using our one hand make beautiful vada. Making the fluffy batter is the key to crisp and fluffy vada. Always grind the Vadai batter with very less amount of water. If you are using mixie for grinding Vadai batter, mixie might turn hot with minimal water so always sprinkle very little ice-cold water and grind. Even for grinder Vadai better, you can use ice-cold water to avoid heat. If you use a small mixie jar for grinding batter in the mixie. If you have soaked a lot of dals, grind in batches to prevent mixie from turning hot. Sprinkle cold water and grind the water. Avoid the blender breaks down (as mortar turns hot). Always Fry Vadai in medium flame. Medhu vada fried on hot oil might turn brown soon but won’t cook through. If the oil is not hot enough or if the urad dal is over soaked, Medu vada can absorb a lot of oil. A slightly thin batter absorbs a lot of oil. That time you can add some rice flour to make correct consistency. For my kids I put like very small ball like one bite sized vadas.
