I use 600ml 椰汁; 400g 糯米粉; around 50g 澄麵; 糖 300g. The use of portion of 澄麵 is personal. If you want the texture to be more firm and easy to cut for pan fry, you may use proportionally more, may be up to 80-100g. I like it softer.
The one I use is -
600ml fresh 椰汁 or canned 椰汁
400g 糯米粉
300g 糖
40g 澄面
I didnt use 菜油 as the fresh fresh 椰汁 contains coconut oil. We can try this. All my friends like. The use of fresh 椰汁 (bought from coconut and spices shop) will make your cake stand out.
