Behind the success of Shiang Thian is Sister Bo Jie, who inherited the recipe of making Ang Ku Kuih (red tortoise cakes), Nyonya cakes, Chinese red eggs and Nasi Kunyit (Turmeric Glutinous Rice) from her mother, Aunty Ngan Yee. The true Nyonya flavour infused by the magical recipes by Sister Bo Jie is unique and no where else to be found.
