Roast the desiccated coconut on medium flame for a few minutes, then remove it to a bowl and set it aside.
Cook the milk and shredded mawa in the same pan while stirring often for a few minutes. Add the sugar and thoroughly mix.
Add rosewater and rose syrup and reheat until slightly thickened.
Stir in the cardamom powder and add the roasted coconut. Cook until the mixture thickens and begins to leave to the surface of the pan.
Transfer the mixture to a bowl and allow it to cool somewhat. Make modaks from it by using a modak-making mold.
Top the modaks with some desiccated coconut. The delicious Rose Coconut Modak are ready to be served.
