All nationalities/localities have their signature dessert. For our part of the world banana fritter is a definite winner. We have the usual form here in Malaysia. It can get pretty boring after some time. I personally cannot recall a stall that offers an 'addictive' version i.e. I have to go back to it again and again.
Once the dough's hurdle is cleared lets talk about the fillings. The type of banana being used is obvious. It must be very sweet and after frying is reduced to a nice soft consistency.
Well the Gandasari Pisang Molen in Bandung is reputed to be the best. Always crowded and never short of folks buying boxes of these heavenly desserts. Highly recommended.
