Vatral Kuzhambu is an authentic South Indian speciality. Vatrals are nothing but sun dried vegetables, which are added to this spicy, slightly sour lentil gravy. It can be made with either one variety or a combination of different vatrals and fresh vegetables. Most popular ones are Sundakkai, manathakkali, brinjal and bitter gourd. Quite easy when you have ready made sambar powder or vatha kuzhambu powder on hand. If not you need to make one and then proceed.
