Firstly, in a kadhai or saucepan add deseeded dates (khajur) and water, and let it simmer on low flame for about 8 to 10 minutes.
Cook the khajur till it turns softer.
Now, add 1 tbsp tamarind paste.
Add 1 tbsp sugar
Add 1 tbsp grated or powdered or cubes of jaggery. You can adjust the sweetness with the amount of sugar and jaggery as per your choice.
Stir and cook till the sugar and jaggery dissolves, simmer on low flame.
Add ½ tsp red chilli powder and ½ tsp coriander powder
Add 1 tsp fennel seeds.
Add salt, mix all the ingredients nicely and stir and cook on medium low flame for 2 more minutes.
Turn off the flame and let the mixture cool down to room temperature.
Now transfer the chutney mixture into the mixer grinder or blender, and grind it to smooth paste.
If needed, strain the ground mixture using the strainer. I have skipped this step as I am using tamarind paste.
Finally, transfer the mixture into the air-tight glass jar or container and use as and when you need it.
