The Silao khaja is a traditional delicacy of Nalanda that has also received the Geographical Indications tag. Silao khaja is known for its taste, crispness and multi-layered texture, which is due to the climatic conditions and water of Silao. The delicious sweet has twelve to sixteen very thin dough sheets placed over each other. It is made from wheat flour, maida, sugar, ghee, cardamom and aniseeds. According to a popular belief, Lord Buddha was served silao khaja by locals of Silao, when he was travelling from Rajgir to Nalanda.
