Add water little by little to the cooked mung, mash and strain the mung water using a sieve. Keep adding water and continue the process of mashing and straining as much mung water as possible till you are left with only a fistful of residue in the sieve. It takes approximately 3 to 4 cups water.
Residues can be used to make parathas.
Heat oil, add cumin seeds, methi seeds and once they splutter add asafoetida, curry leaves, chillies and ginger and sauté.
Add vegetables and sauté further.
Add the dal water, kokum / tamarind paste, salt and jaggery and cook till the vegetables are cooked and the water thickens slightly & is reduced to three fourths.
