Put the tamarind pulp and jaggery in a pan. Over medium heat, stir the mixture till the jaggery dissolves. Now add all the remaining ingredients and cook till the chutney thickens a bit and takes on a shiny appearance.
Allow to cool and use as needed. This chutney keeps in the fridge for a while.
The amounts of tamarind, jaggery, chilli powder and salt may be adjusted as required. This chutney should be sweet, sour and spicy.
