Grind grated coconut coarsely in mixer without adding any water. You can use coconut without grinding too. But you will not get smooth surface/texture on burfis. That's the reason I have ground the grated coconut.
Now heat a non stick pan/heavy bottom wide kadai adding sugar and 1/2 cup of water. Bring to boil stirring continuously till sugar dissolves and starts bubbling.
Continue stirring sugar syrup till you get the single thread consistency, i.e swipe ladle in syrup every now and then to take a drop of syrup between thumb and index finger. If it forms single thread then it is the right consistency. Now add ground coconut and mix well.
Continue cooking coconut in sugar syrup stirring continuously, till it leaves the pan and forms a mass. That is when you need to add ghee, cardamom powder and broken cashews.Mix well and switch off the flame.
Transfer the coconut burfi mixture on to greased tray. Spread it evenly on the tray and mark in to pieces using knife or pizza cutter when it is still warm.
Let it cool completely and remove the coconut burfi/nariyal burfi pieces from the tray. Store in airtight container.
Yummy coconut burfis are ready to distribute with friends and relatives on this Diwali. Wow great Diwali sweet this one!!!!
