My mom's mango chammandi

My mother makes the best Mango Chammandi and it ticks all the right boxes. It sort of defines kerala as it is made with mango, coconut and 'kappal mulagu'. It is my brother's favorite.
Try having it with hot steaming rice and ghee.
Yummy, yum! Heaven!!
Just a word of caution - your breathe will smell of onions.
