In a pot, combine dates, tamarind pulp, jaggery and the spices.
Bring the mixture to a boil and let it simmer for a few minutes. Once cool, remove the seeds.
Transfer the mixture to a blender and blend to a smooth paste.
Strain and pour in a glass jar. Refrigerate and serve for up to 3 weeks.
Notes
It's best to use dates that are naturally soft and plump. If the dates you're using are on the drier side, soak them in some hot water for 10-15 minutes to rehydrate them, and then use them for the recipe.
If you can't find dates, use soaked raisins as an alternative. Sometimes, when I don't have fresh dates, I end up using my homemade date sugar or date puree.
Adjust the consistency of the chutney to your liking. I prefer having this sticky, thick syrup. If you prefer a runny, slightly thin chutney, add more water to the pot.
If the chutney has turned too runny, add it back to the pot and let it simmer over low heat for 10-12 minutes or until it thickens.
Taste and adjust as you go. Once the chutney seems to thicken a bit, give it a quick taste. Add more jaggery if you want it to be sweeter, or add more tamarind pulp if you love that tangy kick.
If you don't have these individual spice powders, dry roast each of these spices on a pan over medium heat, let them cool and then grind them together (or separately).
