Brinjal & Field Beans In Tangy Gravy/Kathirikkai Mochai Kaara Kuzhambu

The name of the dish itself tempts me a lot, i can survive for many days with this super tangy,delicious gravy prepared basically in tamarind extract and with other spices...My mom's signature dish, she also used to add drumsticks and potatoes incase if she run out brinjals in this mouthwater tang..
