In fact, those small holes determine the crispness and shape of the biscuits. During the baking process, the steam inside the cake will escape through those small holes, making the cake crispy and thin as the shape we usually eat.

In the process of making biscuits, dough is rolled flat and flat on a cloth and transferred to a special punching machine. The number of holes and the distance between them depends on the size of the cookie.

If the holes are too close together, the amount of vapor escaping beyond the standard will make the cake dry and hard. But if they are too far apart, the cake surface will appear small bubbles due to the steam trying to escape.
