Use the suggested dal ratio to make Vada. 2. Before making Vada, beat the batter well. Beating introduces air into the batter, making the Vada light and airy. 3. Oil should be hot to fry Vada. Do not fry the Vada in cold oil, as they will burst. Fry the vadas on medium flame only so that their middle part gets cooked properly. 4. Do not fill the vadas too much while frying because the vadas spread a little while frying.
