Dry roast groundnut in low flame till it turns brown and aroma comes.If you crush the groundnut skin then it must peel out from groundnut like paper.It means groundnut is roasted well ,you can remove from flame.
When groundnut reaches room temperature grind them to fine powder ( little coarse powder is also ok).
Add jaggery to powdered groundnut and grind once till jaggery is powdered well and mixes with groundnut.
Heat 1 tsp ghee in wide pan and add the ground mixture , give a quick mix until the mixture forms thick sticky mass.
Now remove from flame , grease your hands with a drop of ghee and make small balls out of the groundnut mixture.
Let the balls rest for 1 hour to set and then enjoy
If the mixture does not form balls and looks dry , Add 1 tsp of hot milk to the mixture and give quick mix . But add milk carefully as adding too much milk will spoil the texture.
