Delicious and sweet tea time snack.Undan pori which translates to ‘fried dough balls’ are a charming, rustic teatime snack from Kerala. They are a staple at road-side chaya kada or small eateries serving tea and snacks.They are also called sweet bonda or gundu (an ode to its cute round shape). Improperly made undan pori can be a literal pain in your teeth but if made properly, they are simply irresistible – crisp on the outside, soft on the inside, and fragrant with banana and cardamom.
