Tamarind-Date Chutney — Sweet-Sour Chaat Base (इमली की चटनी)

North India chaat culture (Delhi, UP, Mumbai street food); the tamarind-date-jaggery combination is documented in Mughal-era culinary records as a condiment for sherbet and meat preparations before becoming the chaat-defining sauce

Imli chutney (इमली की चटनी — tamarind chutney) is the dark, sweet-sour glaze that defines chaat: a thick, complex reduction of tamarind (Tamarindus indica, इमली), dried dates (खजूर, khajoor), jaggery, and a specific spice blend including kala namak (black salt, for its sulphurous, eggy depth), roasted cumin, dried ginger, and red chilli. The sweetness from the dates and jaggery, the sourness from tamarind, the heat from chilli, and the mineralic depth of kala namak together create the chaat flavour architecture that defines bhel puri, pani puri, sev puri, and dahi puri. The chutney must be thick enough to coat rather than drip — it is applied in controlled dollops with a spoon.

Applied to every form of chaat, alongside hari chutney. The interplay of the dark, sweet-sour imli chutney and the bright, herbaceous hari chutney across the same dish is the flavour architecture of all chaat.
