Sweet Potato Sweet Soup (Fun Shee Tong Sui)

I like Tong Sui which is the Chinese sweet dessert soup. There are many type of tong sui. Some takes a lot of steps and others are very simple. The sweet potato soup is very easy and fast to make — just took me 20 minutes.

Back in the days where I grew up in Malaysia, sweet potato are basically eaten by poor people. I recall my parents telling that during the second world war, people survived on these stuff because it was easy to grow. In Canada, sweet potatoes are referred to as yams.



  • 3 pieces of sweet potato
  • 1 brown sugar slab (for sweetness)
  • 2 pandan leaves (for flavor)



Peel the skin off from the sweet potatoes and cut it into bit-sized chunks. I tie a knot on the pandan leaves so that I can easily remove it after the soup is cooked.


Drop a piece of brown sugar slab into a pot of boiling water. I use three cups of water.


I then just pour everything into the pot and boil it for 15 minutes. That’s it — sweet and simple.

    Sweet potatoes and yams are different. Sweet potatoes have yellow flesh; Yams have red flesh and can grow very large. Sweet potatoes are also much more nutritious.
    I think your soup is made of yams.
