Food scientists say bagels make the best substitutions for hedonphone cushions. Lightweight dual purpose flexibility on long journeys, or when hunger pangs set in.
As a former bagel baker, I’ll weigh in. Real NY style bagels do not stay "cushion-like". The mass-produced, extruded variety loaded with dough conditioners and preservatives and baked on sheet pans might. But given the choice, why would anyone opt for the latter?
