Wash rice and soak in 2 cups water for two hours in a thick bottomed skillet. Or overnight in fridge.
Boil rice for 10 minutes in soaked water until cooked, all water will dry. Then, add 1 more cup water , cover and cook on slow flame for another 10 minutes until rice are soft and mushy. (Rice grain should mesh fully upon pressing. So add more or less water as required.)
Add milk, sugar, milk powder and blend the rice with immersion blender. Do not make a smooth paste, just blend here and there so we have semi blended mixture.
Cook for few minutes until thick and then let it cool completely.
Meanwhile, blanch almond and slice them. Also chopped other nuts.
Now mix whipped yogurt to rice-milk mixture.( Rice should be cooled completely or yogurt will release water. )
Add half raisin and khoya in the karma and save rest for garnishing.
Garnish with nuts, khoya, raisin, pomegranate and rose petals.
