How to fry sweet potato balls is soft?

Ingredients: 400g cooked sweet potato, flour 120g, and proper amount of edible oil.

1. First, peel the cooked sweet potato and mash it in a bowl.

2. Add flour to the mashed sweet potatoes and knead well for later use. (The amount of flour in the recipe is less, and the dough is slightly wet and sticky, in order to ensure that you can have a strong sweet potato flavor when eating. )

3. Take a small dose from the kneaded dough, knead it into balls like glutinous rice balls, and knead it all for later use.

4. When the oil pan is heated to 50%, roll the kneaded sweet potato balls along the edge of the pan and shake the pan continuously (this action can not only prevent the sweet potato balls from sticking to the pan, but also make the sweet potato balls roll more and more round, crisp outside and soft inside), and then turn to low heat and slowly fry until the surface is golden, and then take them out.

5. The whole process of sweet potato balls from the pot to the pot takes about 5 minutes, depending on the temperature and the size of sweet potato balls.
