Dry roast sesame seeds till golden brown, Set aside.
Meanwhile melt jaggery syrup in water, strain to remove impurities.
Now take the strained jaggery syrup in a pan and heat it up. Keep stirring.
Keep a plate with water say 1 tablespoon ready - when the jaggery syrup starts thickening just pour a drop in the plate. At a stage the poured drop will not dissolve and will stand firm. At this stage try to roll it into a ball, it will form into a soft ball - that is the first stage dont get misleaded with this stage...It will be chewy when you form balls at this stage.
Slowly if you leave for few more mins, it will start to roll into a slightly hard ball...this is the stage we require, now add roasted sesame seeds.
Give a quick mix, add cardamom powder bring everything together and switch off.
Then take the mixture in a spoon.I used my 1/2 tablespoon measuring spoon....this is done to get all balls evenly sized.
Grease your hands with oil and shape them into balls.
Repeat this for the rest of the mixture. When the mixture turns hard then heat it up, then scrape it and then roll it.
Cool down and then store Sesame Laddu in airtight container.
