Roast the moong dal for 2-3 mins till aromatic
Wash and soak rice and dal separately for 20 mins.
Cook rice, dal, 3/4 of the milk and water in a pressure cooker for 4 whistles on slow heat.
Powder the jaggery. Dissolve in 1 cup of water and stir in continuously on low flame till jaggery is dissolved. There is no need to check for any string consistency of this jaggery syrup
Filter through a tea strainer / muslin cloth to remove any impurities from the jaggery. Cool the syrup to room temperature (very imp). My jaggery was organic, so didn't filter. Cool thoroughly
Mash up the mixture from the pressure cooker finely.
In a pan, add 2 TBSP of ghee, cooked mixture from above. And add the rest of the milk and let it cook on low for 6-7 mins more, keep stirring to prevent it sticking to the vessel.
Add this cooled jaggery syrup into the mixture and mix lightly till it incorporates.
Now add the powdered cardamom, saffron.
Fry cashew and raisins in remaining ghee and pour over the simmered payasam.
And voila ! there you have yummy and slurpy Akkaravadisal !
Serve hot or warm.
