First, take the puffed rice in a pan or a kadai on a medium heat. Roast it until it's crispy. Stir them continuously so that they do not stick to the bottom of the pan.
When the puffed rice is crisp in texture then turn off the heat. It takes only 2 minutes to roast. Now keep them aside.
Now, in the pot or kadai, take jaggery, or you can take jaggery powder with 1/2 cup of water on medium heat.
Heat it until the jaggery melts completely in water. Stir it continuously with a spoon.
Then, continuously heat and wait until the syrup has thickened in texture.
Now, check the consistency of the syrup. Drop the syrup into a bowl and wait for the syrup to freeze. If it does, then turn off the heat of the syrup.
Now, take the puffed rice in a platter or bowl with jaggery syrup.
Mix both ingredients well. So the puffed rice is coated well with jaggery syrup.
Now, make the ladoo by greasing your hands with water or ghee.
Now serve the murmura laddu to your loved ones!
