1Dry roast the sesame seeds in a flat pan on medium heat. Do this till they are a very pale golden color and aromatic.
2Put the jaggery and water in a pan and melt to form a thick syrup. To test if it is done drop a little into a bowl of chilled water. If it forms a ball, the syrup is ready. If not, cook some more. Test again till ready.
3Add the toasted sesame seeds to the syrup and mix well.
Add the ghee and cardamom powder and mix well. Take off from heat.
Grease your palms and when the mixture is still hot (but cool enough to handle) take enough in your hand to form a golf ball-sized lump. Roll between your palms till smooth. Lay on a greased plate to cool. Repeat till all the mixture is used up. The laddoos will soon harden to candy-like texture.
4Store for up to 10-15 days in an air-tight container.
