After half an hour take the Chenna, Knead for 8-10 minutes till Chenna is soft and smooth.
Now add 1-2 tsp of rose essence or pink food color to get nice color and flavor to the pink jamun or rose jamun knead well again. Shape them as small cylindrical balls.
Now switch on the stove with syrup when it starts bubble add the prepared jamun to it. Cook for 10 mins in high heat and keep covered.
After 10 mins open the lid and check the size got doubled. This is the good sign that the jamuns are cooked well. Switch off the heat. If you have not added rose essence while making jamuns add it in the syrup once you turn off the stove.
