In a dry pan add til (sesame) seeds.
Let them roast for 3-4 minutes till they start to splutter. Do not brown them a lot as they will start tasting bitter. Remove and set aside.
In the same pan add ghee and jaggery.
The jaggery will start to melt; reduce the flame to the lowest setting and mix the jaggery intermittently.
The jaggery will melt completely and start to bubble. It takes about 10-12 minutes for this stage.
Then drop a small amount of the molten jaggery in a bowl of cold water. If it forms a hard ball that can be broken into two without any strings, it is ready. Else cook for another couple minutes and check again.
Then transfer the sesame seeds back into the cooked jaggery. Turn down the flame.
Mix well till all the sesame seeds are coated with jaggery. Add the cardamom powder and mix.
Then transfer the mix on to a parchment paper
Place another parchment paper on top and roll into a thin sheet. I rolled it to ¼ inch thickness. The thinner it is the crisper it will be.
Carefully peel the top parchment paper.
Using a sharp knife mark out the pieces immediately. I made them 1.5 inch by 1.5 inch.
Then cool completely for 60-90 minutes before breaking the pieces apart.
Transfer to an airtight container.
