In a kadai or pot, add tamarind (seedless), pitted dates, powdered jaggery along with 2 cups of water.
Boil them until they turn soft and mushy. It will take around 10-12 minutes. You may add an extra ½ cup of water if the tamarind date mixture needs more water to soften.
Next, add all the spices like, red chili powder, cumin powder, coriander powder, dry ginger powder, and black salt. Stir well and cook for another 2-3 minutes until all the flavors are absorbed.
Once the chutney has thickened to your desired consistency, Turn off the flame and let the mixture cool completely to room temperature.
Transfer the mixture to a blender and blend until smooth. You can also use an immersion blender to blend.
Place a sieve (fine mesh strainer) over the bowl and add the pureed tamarind mixture. Using the back of spoon or spatula, strain the tamarind and date pulp, discarding the fibers left in the strainer.
Date tamarind chutney is ready to be served.
