Dry roast rava and pottukadalai for 30 secs each to just heat it up.
Heat a pan with sugar and ½ cup water. Boil until you get 1 string consistency.
Add coconut and again bring to boil for 2 minutes.
Add rava, pottukadalai and continue cooking. Once thick, add 1 tablespoon of ghee and mix.
Keep mixing until the mixture starts to leave the sides. Add remaining 1 tablespoon ghee and powdered cardamom.
You will see the whole mixture bubbles raised, frothy and white.
Keep a greased pan ready. Pour the mixture immediately and level.
Let it cool down a bit. When it is lukewarm, invert and tap gently. Cut into squares.
