Take the Urad dal and Clean, wash and soak it in enough water for at least 1 hour

Drain them and add it with asafetida, chilies and 1/4th cup of water 

Blend it in a mixer to a smooth paste

This should be added with coriander, cabbage, peas, onions and salt and mixed well

Your fingers must be wet and take some batter to make a hole in the centre using your thumb

Slide the vada  into the hot oil gently and deep-fry

Keep it on a medium flame till it turns golden brown in colour on all sides

Repeat the process with the remaining batter 

Drain all the Vadas on absorbent paper
