Pressure cook the cauliflower and carrots with little water, turmeric and salt on medium flame on one whistle. Allow the pressure to go by itself. Add the frozen green peas into it and close.
Grind all the ingredients under "for grinding" into a smooth paste.
Add the paste into the cooked vegetables and simmer till the raw smell is gone. Sprinkle the garam masala and switch off.
Heat ghee, splutter the cumin. Add the dry chillies and curry leaves, fry slightly and add back to the gravy.
Notes
This gravy thickens as it sits. Adjust with hot water.
