Beetroot Puli Kulambu / kuzhambh

I love puli kulambu esp for the weekend meals. It is really gives refreshing break to normal sambar with dhals. I had left over 1 beetroot in the fridge. Was wondering what to do with it. Then I remembered seeing Vathakuzhambhu at Jeyasrhris space. I wanted to try out too. but I did it with my own way. What a perfect combo of spices.. this tasted heaven.
