The holes in crackers aren’t just for aesthetic purposes; they have a specific function. When baking crackers, these “docking holes" help vent steam. This both reduces air bubbles and stops the bread-like dough from rising. How are the uniform holes made in the cracker dough? After rolling the dough out flat, a special machine called a docker pricks the holes. Without these holes, the dough wouldn’t bake evenly and the middle of the cracker would rise, like cookies do. Docker holes allow crackers to remain flat and uniform.
