Rinse the chana dal thoroughly and soak it in water for about 2 hours.
1 cup chana dal (split Bengal gram), water
Drain the soaked dal and transfer it to a pressure cooker. Add fresh water, turmeric powder. Cook for approximately 3-4 whistles, or until the dal is soft and well-cooked.
1/8 teaspoon turmeric powder, water
Once the pressure is released, open the cooker and drain any excess water from the cooked dal.
Transfer the cooked dal to a pan and place it on medium heat. Add jaggery to the dal and mix well.
1 cup jaggery
Cook the dal and jaggery mixture on medium heat, stirring continuously, until the jaggery melts and blends with the dal.
Add cardamom powder, nutmeg powder, and saffron strands (if using). Mix well and cook for a few more minutes until the mixture thickens.
1/2 teaspoon cardamom powder, 1/8 teaspoon nutmeg powder
Remove the pan from heat and let the filling cool completely.
