Purple Sweet Potato Ang Ku Kueh 紫薯红龟糕

Ann Low June 17, 2013 130 Comments

Ang Ku kueh is one of the popular Asian Snacks among the Chinese and Peranankan. Ang Ku kueh literally means Red Tortoise Cake. It is moulded to resemble a tortoise shell and is presented resting on a small piece of banana leaf. The Chinese traditionally believe that eating this ‘Ang Ku Kueh’ would bring longevity to those who are eating it and bring about good fortune and prosperity. But my ‘Ang Ku Kueh here is in the shape of a peach shape (add in the Chinese word ‘tao’ 桃) and the purple colour is from the purple sweet potato.
I’ve to thank sweet May of 厨苑食谱 for sending me this double sided pretty mould which has the shape of a peach on one side and the word ‘shou’ 寿 on the other. These two shapes bearing the ‘shou tao’ 寿桃 should be made in red which symbolises a long, healthy life with great fortune for many generations.

I adapted the recipe from May with slight adjustment. This version is definitely healthier and easier to make compared to the one I made last time whereby the dough was made with coconut milk and the mung beans fried with shallot oil. I like this recipe as the dough skin and filling are smooth and soft. But my kueh looks quite transparent due to the thin dough skin. If you want to try this recipe and make a perfect ang ku kueh remember to make a thicker dough skin. Adjustment will be based on your own ang ku kueh mould.

I like your recipes. I have tried the purple sweet potato snowskin mooncakes last year and it was really good. Can I use this Muang bean filling method for mooncakes? I noticed your Muang bean mooncake recipe is different .

Hi Christina, yes you can to use this for mooncakes but can only last for a few days because this is different from the mung bean mooncake filling. The mung bean paste used more water and takes longer time to cook.
