Yes, this cilantro mint chutney freezes very well. When I have lots of fresh coriander and mint at my home, I make a large batch of this chutney and freeze them in ice cube trays. The next day I take out frozen chutney cubes and put them into a ziplock bag. These come in handy when you have sudden guests at home or have pani puri cravings. You can either thaw by keeping frozen cubes in the refrigerator overnight or using a ‘frozen vegetable’ setting in your microwave.
