Biscuits are one of the most favorite and commonly consumed food products around the globe. They are simple, inexpensive, and comforting and have a special position in our daily lives, right from the time of tea to the busy hours of the day. Whether they are sweet or savory, crunchy or soft, biscuits do not have any boundaries of age, culture, or geography, and thus are one of the most universal foods. Biscuits today come in a variety of forms, such as butter biscuits, chocolate cookies, and digestive biscuits.
Options are now available that are made from whole grains, millets, and oats and have less sugar. However, when we consume biscuits, we do not realize that even the formation of biscuits involves so much science. One of the most fascinating and observed facts about biscuits is that there are small holes present on their surface. These holes are not just for show. They have a very important function when they are being baked.

Why do bakers add holes in biscuits during the baking process?
Biscuits begin as dough that is prepared with simple ingredients like flour, sugar, fat, water, and leavening agents. When put in the hot oven, the actual process begins. The heat causes the moisture in the dough to turn into steam while the air in the dough expands. If this pressure is not released, the biscuit could develop unevenness, cracks, or blisters, or fail to retain its flat shape. All these could affect the texture and appearance of the biscuit, making it less crispy.
To avoid such problems, the biscuit dough is punched with small holes before baking. These holes are referred to as docking holes, and they help in the removal of steam and air from the dough during baking. The docking of the dough helps in the even baking of the biscuits and also ensures that they retain their texture. This is particularly important for plain, salted, and cream biscuits, which should be crisp and firm to the touch.
How do docking holes help in the mass production of biscuits?
Another important role docking holes play is in ensuring uniformity. They assist in retaining the biscuits’ thickness and shape even when exposed to high temperatures. This is why biscuits in a packet are always similar in size, color, and texture. In large-scale commercial production, such consistency is crucial. The holes ensure that the same crunch is experienced regardless of when and where the biscuit is made.
Interestingly, not all biscuits need docking holes. Soft, chewy, or cake biscuits require other baking methods and textures, where the importance of steam escape is not as significant. Some sweet biscuits may have holes, depending on the recipe.
Docking has been practiced for centuries in baked goods to enhance texture and shelf life. This seemingly minute detail in design is actually the culmination of baking experience and food science over the years.

The next time you enjoy a biscuit, remember that these minute holes are doing more than just catching crumbs. They are working tirelessly to ensure the perfect crunch, shape, and texture.
