In a pan add the makhana and start roasting it.Roast it in low flame.If you want to verify if its done, just pop one or 2 in your mouth it should be crispy then its done else roast for some more time.Set aside.
Take sugar in a pan,add water to it.Heat it up.
Add cardamom and dry grinder powder,keep cooking.Sugar will first dissolve then start to thicken up.
Keep a small plate of water and keep checking.When you add few drops to the plate first the syrup will get dissolved after sometime it will stand still in water without dissolving and try to gather and form a ball,it will form a little loose ball,this is the right consistency we want.
Add roasted makhana, toss well and switch off.
Mix well and set aside for 10mins.Now you can see a white layer covering up the makhanas yes its perfect then!
