Why Do Crackers Have Holes?
The holes let steam escape so that crackers can maintain their shape! Moon Shot Snacks's website states that "without docking holes, crackers wouldn’t look or taste like crackers at all! As crackers are baked, they’re filled with air. This causes the cracker to stretch and can change its texture. When air bubbles go unchecked, they can even cause explosions! 🤯
When a cracker has docking holes, steam is able to escape so the cracker doesn’t stretch… or combust. You may also notice that some crackers are puffy. They’re designed with fewer docking holes so they can fill with air during the baking process."
