Separate 10 g mint leaves from their stems. Coriander stems are more delicate, so you can use those, as they pack a ton of flavour (although you should remove any extra tough/thick ones). Chop the mint and 20 g coriander.
Add the herbs, 1 green finger chilli, 1 clove garlic, ½ teaspoon minced ginger, ½ whole lemon, juiced½ teaspoon cumin seeds, 2 ice cubes, and 2 tablespoons cold water to your mixer grinder/blender. Pulse in small bursts until you achieve a smooth texture.
Notes
Blend the chutney only until it's smooth — over blending can make the chutney bitter.
