Notes
Easy method to separate leaves from stalk is wrap drumstick leaves in a paper and keep it aside for few hours / overnight . Upon opening .. you will see that most of the leaves have already separated from the stalk !!
If your dal gets thin and you don't have cooked tuvar dal left out , you can add 1-2 tbsp diluted besan ( gram flour ) to thicken it . Boil well .
