Sweet Potato Balls - Southeast Asian Recipes (2024)

Sweet potato balls are a popular bite-sized snack in Taiwan. They are crispy on the outside and chewy on the inside. Made with tapioca flour, the texture on the inside is bouncy, very similar to that of tapioca pearls in bubble tea.

Sweet potato balls come in many variations throughout Asia. The snack is made using sweet potatoes you can get at your local supermarket. Not to mention, it is a vegan snack too. No wonder foodies are willing to wait in long queues at night markets or at a street food stall just to get this freshly fried snack.

Each variation of sweet potato snack differs slightly by one or two ingredients. In this recipe, we will explore Taiwan's version of sweet potato balls. The QQ consistency makes them stand out and is also probably the reason why they are extremely popular.

The QQ consistency

The Taiwanese version has typical characteristics as in many of their snacks - bouncy and chewy. This consistency is so pronounced in their cuisine that they even coined a term calling it QQ.

Apparently, the term comes from the the local Minnan dialect. The word ‘khiu’ 糗which brings the meaning soft, springy or elastic sounds almost like the alphabet Q. Hence, QQ!

If you are from Malaysia or Singapore, you'll recognize the consistency. It's very similar to glutinous rice cake (kuih bakul).

Since it uses tapioca flour, it has the exact bounciness or texture like the tapioca pearls in bubble tea. Coincidentally, bubble tea is from Taiwan. I suppose if boba is fried, it may taste just like this snack.

Type of sweet potatoes

There are many types of sweet potatoes available. As you have already seen from the photo, it's the common orange type that is used. You can use other types of sweet potatoes and they will work just fine. The colour of the snack will highly depend on the type of the root vegetable used.

Japanese sweet potatoes (satsuma-imo) may look similar to the regular type but they are naturally very much sweeter. So, if you do choose this as your choice of the main ingredient, do reduce the sugar content by 5 grams or more.

Important tip when steaming

Cut sweet potato into thin slices to quicken the steaming process. Droplets of water might fall onto the sweet potatoes during steaming. Remove any excess water with a kitchen towel to prevent additional moisture to the mashed potatoes as it might change the content of liquid in the dough later.

Tips to follow when frying

You need to have a few tricks up your sleeves to make the best tasting sweet potato balls.

Firstly, start frying them with oil which had already been heated over low heat. Frying at a high temperature initially may cause them to brown too soon leaving the insides uncooked.

The other tip which every sweet potato balls street vendor in Taiwan practises is the act of pressing the balls while frying. It needs to be done for at least 3 times. This makes the balls expand in size and it's noticeable almost immediately.

What makes them crunchy?

Corn flour! When using only tapioca flour, the balls turn soft after a while. Adding a bit of corn flour makes a big difference to the final outcome. The outer layer of the ball becomes crunchy and gives a nice cracking sound as you sink your teeth into it.

You will fall in love with the sweet potato balls at first bite. We all know for a fact that crunchy food is always tasty. Even science backs the idea!

Comparison of sweet potato balls

The common sweet potato balls do have a mildly crunchy outer layer but they can never beat those with corn flour in them. Besides the crunchiness, there is also a notable difference on the inside. Those with corn flour have a larger hollow space while the version with only tapioca flour is denser.

For most Taiwanese restaurants and street food vendors, they do not use the additional flour. If you are one of those who do not enjoy super crunchy food, then omit the corn flour and use only tapioca flour. This is the recipe.
