Take jamun mix in a bowl and mix well so there is no lumps.
Now add water or milk and make into a soft dough.
Take ¼th of the dough separately in a bowl and add in sugar, cardamom powder and green colour. Mix well.
Now divide both the dough into equal portions.
Take the white portion dough and press it slightly. Place the green ball in the center and cover it up.
Shape it into smooth round ball and then into log shape.
Heat oil for frying on a medium heat. Fry the jamun till they are golden. Drain and set aside.
After 5 mins fry it again till it get black.
Now make the sugar syrup. Place sugar and water in a sauce pan. Mix it and bring it to boil. Simmer till it turns sticky.
Now drop the jamuns in the syrup and let it steep in the syrup for 6 to 8 hours.
Reheat the syrup often to keep the syrup warm so the jamun will absorb the syrup a lot faster.
Now serve.
Notes
1)Fry jamuns on a low flame so it get cook evenly.
2)Always keep the syrup warm so it absorbs the syrup faster. I reheat the syrup every hour or so to keep it warm.
