Take 2 medium-sized dudhi and remove the skin with a peeler. In a mixing bowl, spread a cotton cloth and grate the dudhi using a large-hole grater. You should have about 4 cups or 500 grams of grated dudhi.
Next, use the cloth to squeeze out the water from the grated dudhi and set it aside. In a pan, add 2 tablespoons of ghee and the grated dudhi. Stir continuously and cook the mixture on medium flame for 3-4 minutes.
Then add ½ cup of milk and mix well. Cover and cook the mixture on low flame for 3-4 minutes until the dudhi is properly cooked and soft.
Now add ¾ cup of sugar and a pinch of green food color. Mix well and cook the mixture until the sugar is completely absorbed. Then add ½ cup of milk powder, ½ cup of desiccated coconut, and a pinch of cardamom powder. Mix well.
Continue cooking until the mixture thickens and starts leaving the sides of the pan. Add 1 tablespoon of ghee and mix well. Switch off the heat.
Transfer the ladoo mixture onto a plate and let it cool slightly. With greased hands, start shaping the mixture into ladoos and coat them with desiccated coconut.
The dudhi na ladoo is ready. Refrigerate for 30-40 minutes to set properly. Enjoy dudhi na ladoo for up to 15-20 days when stored in an airtight container in the refrigerator.
