Date (Kajur) chutney

Another chutney I learnt from k's mom:

Ingredients:
A box of dates, 2 teaspoons jaggery, a teaspoon black salt (adjust as needed), a teaspoon amchur (dry mango powder)

Recipe:
Boil the dates in water in a pressure cooker for 10 minutes (until they become soft enough to crush completely). Let cool and mash it in a food processor with enough water to give it a chutney consistency. Add the remaining ingredients and mix well. Refrigerate.
