I tried this Date Tamarind chutney found on google on a blog . And it came out very well. ingredients (measuring cup used, 1 cup = 250 ml) ½ cup tightly packed seedless tamarind ½ cup seedless dates ½ cup powdered or grated jaggery or as required - adjust as per your taste 2 cups water ½ tsp roasted cumin powder ½ tsp coriander powder/dhania powder ½ tsp dry ginger powder/saunth/sooth ¼ or ½ tsp red chili powder or 1 dry red chili black salt or rock salt as required. Steps: in a pan, take the tamarind, dates and water. cook the tamarind and date for about 8-9 minutes on a low flame till they soften. now add the powdered jaggery and continue to cook. let the jaggery dissolve and the mixture thicken a bit. add all the spice powders - red chili powder, coriander powder, dry ginger powder and roasted cumin powder. stir & simmer for a further 1-2 minutes more. season with salt. let the chutney mixture cool down. In a chutney grinder or small blender, grind the this whole mixture till smooth. add some water if required while grinding. strain the chutney through a strainer. store the tamarind date chutney in an airtight bowl or container in the refrigerator and use it when you make chaat at home.
