Wash the mint leaves.
Peel and chop the raw mango.
Cut jaggery in small pieces.
Dry roast cumin, fenugreek and dry chilli (if using the red dry one).
Add all ingredients to the mixer jar and grind to a smooth consistency. You should be able to grind the chutney without any extra water. However, if you need to, add a very small amount – a teaspoon or two.
