We loved Vietnamese dessert. Often time when we went up to Denver, we would go to a Vietnamese bakery shop to buy some of the kuih (Asian steamed cake), "tofu fah" and cups of sweet dessert like the above. It came with several variety and it was hard to pick a favorite, but often time I would pick one loaded with beans, sweet potato, sago and taro. I don't know how they really make theirs but I know it is sweet and covered with coconut milk.
This is my version and it tasted just like the one sold at the store. It is not difficult to make but involved a few steps like cooking the tapioca pearls or strips first and steaming the sweet potato or taro if used. Then, you just mix it all together and place into an individual serving bowl or cup and refrigerate until serving. It is best eaten on the same day as the tapioca strips might harden when kept in the fridge for too long. If you make this, please feedback to me ya! Enjoy!
