I have noticed the disappearance of the bran muffin (my autocorrect just tried to change that to bean muffin) and as a test asked the young woman at the cafe where I got breakfast if they ever had bran muffins. “Never heard of it,” she said. “What’s in it? What does it look like?” She’s 24. The customer behind me laughed. I asked her if she remembered the last time she saw one, and she shrugged. “The 1990s?”
