Wash & dry the coriander and mint leaves well, and roughly chop the coriander leaves before measuring the greens out.
In a mixer, blend the coriander & mint leaves, with peanuts, cumin seeds, green chilies, salt & water, till it forms a smooth paste.
Once done, transfer the chutney into an ice-cube tray (or multiple ice trays, depending on the size of the trays and quantity of chutney).
Cover the tray with a lid or plastic cling wrap, and place it in the freezer till the chutney is frozen solid.
Once the green chutney cubes are totally frozen, remove from the freezer, and transfer the cubes into a freezer safe ziplock bag.
Seal the bag, after ensuring to remove all the air out from the bag.
Label & store the bag in the freezer for future use.
The green chutney cubes store well for 3-4 months.
