Take the curd and beat till it becomes a fine batter after adding water

Now add little salt to the mix

Take the vegetables (Cauliflower or potato) and boil them

Add them to the curd mix

Now the entire thing should be mixed well

Take a pan or round bottomed ladle and add 1-2 tsp oil in it 

Heat the oil

This should be added with cumin seeds, mustard seeds, urad dal, asafetida and halved red chillies

Once the mustard seeds start to crackle, add the curry leaves and remove the tadka from the flame

This Tadka must be transferred to the curd-vegetable bowl and mixed well

Sprinkle a pinch of salt to get the required taste
