Soak jaggery in 1 cup of warm water and then crush it well.
Then, heat it up until it is slightly thick. Cool down, strain and keep aside. You don't have to check for string consistency.
Wash and soak the rice. Add 2 cups water and pressure cook for 3 whistles. Rice should be cooked till soft but not mushy as we want the grains to be seen.
Measure and add jaggery syrup.
Mix well and cook in low flame till the jaggery syrup blends well with the rice. Once this is done, add grated coconut.
Mix well and cook for 2 mins, then add ghee little by little.
Keep mixing, at one stage the payasam will get thick and saucy in consistency. Add roasted cashews, cardamom powder, dry ginger powder and switch off.
Serve hot.
