Why does bread have holes?

Bread! It’s good stuff, no matter how you slice it. But why do slices of bread have holes in them? Are there bread moles who tunnel through baguettes? Invisible worms in the whole wheat? Chipmunks chewing on the ciabatta? We asked food scientist David Domingues  to help us find the answer. Got a question that you knead us to look into? Send it to us atBrains On.org/contact, and we’ll find the answers where you yeast expect them! See omnystudio.com/listener for privacy information.
