Taitung Sweet Potato Balls | Taitung Signature Dish

Taitung's coastal sandy soil is loose and well-drained, with abundant sunlight, producing sweet potatoes with especially high sugar content. Mash those local sweet potatoes, mix in sweet potato starch and shape into small balls, then drop them into hot oil — the key is pressing them repeatedly with a ladle while they fry so the balls puff up and expand. Out of the oil, the shell is paper-thin and crackly like a balloon: give one a light squeeze and it springs back. Bite through and the inside is soft and pillowy, carrying the natural sweetness of the sweet potato. The nights at Tiehua Village run on these little spheres.

What is Taitung Sweet Potato Ball

Sweet potato balls are made by mixing cooked mashed sweet potato with sweet potato starch (or tapioca starch) in the right ratio, adding a small amount of sugar and salt, and rolling the dough into balls about 3 to 4 centimeters in diameter. They are fried in oil at around 160 degrees Celsius, with the cook continuously pressing them against the side of the wok with a ladle to force the balls to puff up and become hollow. The Taitung version emphasizes the use of local coastal-zone sweet potato varieties with higher natural sugar content, so the finished balls are naturally sweet without needing added syrup. The surface is slightly wrinkled and springy, and the interior is honeycombed with air pockets — far lighter in texture than the frozen commercial versions.

Tiehua Village in Taitung City is the most representative nighttime creative hub in the city, hosting regular weekly markets and live music performances. The peripheral vendors form a natural cluster of evening street food. Sweet potato balls — fried to order, cheap, and requiring no utensils — have become one of the most common mobile snack stalls at Tiehua Village at night, and they also appear at Taitung's tourist night market. The Taitung County Tourism website's night market food guide lists sweet potato balls as a representative item of Taitung's nighttime food scene.

How to eat it like a local

🔥

Eat within three minutes of leaving the oilThe shell is at its crispiest within three minutes of frying. Wait any longer and the crust softens and the textural contrast disappears. Grab them and eat immediately — that is the whole point of ordering them freshly fried.

Visiting tips

Tiehua Village vendors are not present every day. On rainy days or non-market weekends attendance is much lower. Check Tiehua Village's official announcements to confirm market dates before going.
Sweet potato balls are a year-round night-market food with no seasonal restriction, but crowds are at their peak during the summer holiday season, so expect longer waits.
