Crackers have holes in them for a reason

Holes are not just in crackers for the looks, they actually serve a purpose! Without the holes, crackers would not bake properly. Cracker dough contains lots of air bubbles that expand while in the heat of the oven. The holes, known as docking holes, are purposefully put in the crackers by a machine called a Docker. The holes allow for air to escape from the cracker so that it can bake properly and evenly. This also ensures that the crackers come out flat.
