Let the pineapple cool completely. Keep aside some pieces of pineapple and grind the rest into a coarse paste in a blender.
In the mean pressure cook the sago beads with 2 cups of water and let the pressure cooker give out one whistle. Do not over cook as sabudana will completely dissolve.
In a heavy bottom pan boil the milk and let the milk reduce to half.
Once the milk is reduced and slightly thick add the remaining sugar and cooked sabudana and give it a good mix.
Bring it to a boil and thicken.
Switch off the flame. Let the payasam cool down for 15 mins.
Once it has cooled down, add the pineapple pieces and the pineapple paste to it and give it a good mix.
Heat 1 tbsp of ghee in a small pan and add raisins and cashews to it. Once the cashews turn gold and the raisins plump up add it to the payasam.
Refrigerate the payasam and serve it cold.
