Add all the ingredients, except water, to a mixie jar. Grind to a coarse but wet chutney consistency. Add water little by little while grinding, adjust according to your preferred consistency.
Tempering
Add vegetable oil to a heavy bottomed pot and allow to heat up on medium flame. Add mustard seeds and allow it to splutter. Next add urad dal and chana dal and allow to roast. Once the dal starts to become golden, add dry red chilli and curry leaves. Fry till fragrant and curry leaves are crunchy.
Remove from heat and add it on top of the chutney. Mix well right before you serve.
