Heat half quantity of ghee in a cooking pan and roast cashews in it. When they turn little brown, remove from pan and add rava. Sauteeing constantly roast it till nice aroma wafts out.
Transfer roasted rava from pan and add 1.5 cups of water to it. Include mango puree and soaked saffron strands to the water and bring it to boil. Reduce flame to the lowest and include roasted rava to the boiling water while stirring continuously.
Ensuring no lumps have formed and rava has absorbed all water, add sugar and cardamom powder. Combine well.
As sugar dissolves, the cooked rava turns watery again. Continue cooking till it turns thick. Add remaining ghee and roasted cashews. Combine well. When rava kesari leaves the sides of pan, switch off the flame.
An absolute visual delight mango kesari is ready. Easy dessert and it can make ordinary meal as extra-ordinary.
