Fried sweet potato balls

Miss Taiwan night street food.... have to ownself try making it at home. I bought the Vietnam yellow Sweet potato from Ntuc to make, so it is not orange one. This kind of sweet potato is very sweet and fragrant.

Ingredients:
250g sweet potato
40g sugar (depend on sweetness of the sweet potato used)
120g tapioca starch 
Warm water (depends)

Steps:

1. Cut the peeled sweet potato into slices and steam for 15 min to soften.

2. Press the sweet potato using spoon or fork to mash it while is still hot.

3. Add in the tapioca starch and some warm water to make a smooth dough. The amount of water to add depend on the kind of sweet potato you used. Some become more wet after steaming. 

4. Cut into small dough and roll into ball.

5. Heat up a pot of oil. Use low heat to fry the sweet potato balls. Keep pressing the balls down. When you press down, the ball will become bigger. 

6. After 10 min of frying in low heat, use high heat to brown the surface and is ready to serve.
