Medu vada is the doughnut of the South Indian tiffin room — shatteringly crisp outside, cloud-soft inside, with a hole in the middle that exists for one reason: so the sambar can reach every bite. The secret is not in the ingredients, which are few, but in the batter: ground thick with almost no water, then beaten until it holds air. Get that right and the vadas fry up light instead of dense, every single time.
Ingredients
Method
- Drain the soaked urad dal completely and let it sit in the sieve for 10 minutes — surface water is the enemy of a thick batter.
- Grind the dal in a wet grinder or a strong blender in short bursts, sprinkling in only 2 to 3 tablespoons of ice-cold water as needed, until you have a smooth, very thick, fluffy batter. It should hold its shape on a spoon, not pour.
- Tip the batter into a bowl and beat it with a whisk or your hand in one direction for 2 to 3 minutes to work in air. Test: drop a small blob into a bowl of water — it should float. If it sinks, beat a little more.
- Fold in the green chillies, ginger, curry leaves, pepper, cumin, asafoetida, onion (if using), coriander and salt. Mix gently so you do not knock the air out.
- Heat oil in a kadai on medium heat — hot enough that a tiny drop of batter rises to the surface steadily and sizzles, but does not brown at once.
- Wet your palm, take a lemon-sized portion of batter, roll it into a ball, flatten slightly and poke a hole through the centre with your wet thumb. Gently slide the vada off your palm into the hot oil. Fry 4 to 5 at a time, not more.
- Fry for 2 to 3 minutes, turning once or twice, until deep golden and crisp all over. Drain on kitchen paper or a rack.
- Serve immediately with sambar for dunking and coconut chutney on the side — vadas wait for no one.
Notes
The float test never lies: a batter that floats fries up light; a batter that sinks will make heavy vadas. Beat in more air instead of adding water.
Ice-cold water while grinding keeps the batter from heating up, which keeps the vadas crisp rather than oily.
If the batter ever turns runny (too much water while grinding), fold in 1 to 2 tablespoons of rice flour to bring it back — the vadas will still be good.
Leftover batter keeps a day in the fridge; bring it back to room temperature and beat once more before frying.
