Pan-Indian; hari chutney in some form is found across every Indian culinary tradition from Kashmir to Kerala; the specific coriander-mint-chilli combination is North Indian in origin, spread through chaat and tandoor culture
Hari chutney (हरी चटनी — green chutney) is the most-consumed condiment in Indian cuisine: a freshly ground paste of coriander (Coriandrum sativum), fresh mint (Mentha), green chilli, garlic, ginger, lemon juice, and salt. The ratio of coriander to mint determines the character of the chutney — a higher mint proportion produces a cooler, more refreshing result; higher coriander produces a herbier, more earthy flavour. The technique of wet-grinding (blender or stone grinder with water) versus dry-grinding changes the texture — wet-ground chutney is smoother and lighter green; stone-ground is darker, coarser, and more oxidised. Fresh chutney must be used the same day — refrigerated overnight it turns brown and loses its volatile herb aromatics.
Used as a dipping sauce for chaat, snacks, samosa, pakora, and tandoor preparations. Applied as a spread on vada pav, sandwiches, and rolls. Its versatility makes it the most universally applicable Indian condiment.
{"Coriander to mint ratio for maximum versatility: 3:1 (three parts coriander to one part mint) — this produces a flavour that works across all chaat, tandoor, and grilled contexts","Stem-inclusive for coriander — the stems carry intense flavour; wasting them produces a paler, lighter chutney","A pinch of sugar and roasted cumin balances the heat and adds depth — the cumin bridges the herb and chilli","Grind with minimal water for maximum concentration — diluting with water produces a liquid chutney that separates"}
A practitioner's proportions: 1 bunch coriander with stems : ½ bunch mint leaves only : 3–4 green chillies : 2 cloves garlic : 1 inch ginger : juice of 1 lemon : ½ tsp roasted cumin : salt. The colour of excellent hari chutney is deep, vivid green — if it appears pale or yellow-green, the herbs are stale. Adding a tablespoon of fresh yoghurt to the chutney thickens and enriches it for pairing with tandoori preparations (less bright but creamier).
{"Making the day before — the chlorophyll in the herbs degrades overnight and the bright green turns brown; make fresh","Too much water in the blender — produces a thin, separating chutney that doesn't adhere to food","Skipping the lemon juice — acid both preserves the green colour (briefly) and provides the essential brightness"}
