I learned that it is best to use high-gluten flour to make fried dough sticks, because high-gluten flour contains higher gluten quality and protein content, which can make the fried dough sticks crispier, chewier and taste better.

All-purpose flour can also be used, but the texture may be slightly soft.

It is not recommended to use low-gluten flour because its gluten quality and protein content are low, and the resulting fried dough sticks will not taste good.
