What's the name of the crispy inside the pancake fruit?

According to Baidu Encyclopedia, fruit grates, also called fruit grates, are a local snack in Tianjin and are often associated with pancake fruit. Because it belongs to the same kind of fried food as fried dough sticks (commonly known as fruit), it is named fruit grate. So the crispness in pancake fruit is called fruit grate.

The fruit grille tastes a little salty and crisp. The main ingredients are flour, cooking oil, salt, baking soda and water. The ground fruit can be eaten alone, or sandwiched in pancake fruit or pie. Fold the fruit grate in half and put it in the pancake with the fruit (fried dough sticks), which becomes the pancake fruit.
