Dry roast the sesame seeds till they start crackling a little and keep aside.
Grind or cut jaggery coarsely and mix with water and bring to boil, lower the gas and simmer till it becomes a thick syrup. The test here should be to cook it till forms a ball when you drop a little in chilled water.
See the big ball kinds in the above water, like that. Ignore the brownish liquid that was formed by the test I did before, when the liquid was not cooked. At the time it will immediately spread and color the water like you see. It will take approx of 7-10 minutes.
At this stage, add the sesame seeds, ghee and cardamom powder and mix well.
Immediately pour over a greased tray and leave for setting
Leave it for setting for about 30 minutes and cut into desired shapes and of course eat and lift your senses!
