My photo looks a little different from the recipe because I used lily bulbs instead of lotus seeds. I used one 12 pkg azuki beans and then added in the lily bulbs and 6 oz rock candy in Step #3. It is delicious but I enjoy it more as a breakfast (similar to a sweet oatmeal) than a dessert.
This soup is great but the recipe doesn't really tell you how to cook the tapioca or what kind of tapioca to use (like flour or pearls). I used tapioca pearls but by the time the beans were done the pearls weren't fully cooked. I searched the internet and found out that it's best to cook the pearls separately, dip them in a solution of water and brown sugar to give them a sweet taste, and finally add them to the dessert. I also recommend adding coconut milk to the soup to make it more flavorful. This is what I did and in the end it turned out pretty good.
