Take a medium size fully riped yellow pumpkin piece. Remove the seeds and scrap the skin. Cut it into medium size bits. Add little water and cook till it is soft. Mash well.
In a kadai put a teaspoon of ghee and fry the cashew nuts and keep aside. In the same kadai, put one more teaspoon ghee and fry the rawa and add the milk. Let rawa cook in the milk on low flame. When rawa absorbed all the milk, add the mashed pumpkin and fry for five minutes. Add sugar and stir well. Cook till it thickens. Add remaining ghee, fried cashew nuts and cardamom powder and mix well. Transfer it to a greased bowl.
