We call rolls "yeast rolls" in my family. As opposed to? Baking powder biscuits? But those are biscuits, not rolls. Are all rolls yeast rolls?
What are the things that are unique to your family that you've always taken for granted? Have you ever found yourself in the disconcerting position of being caught in an oddity that you thought was common to every family or region? I'll never forget how flustered I got having to explain Philadelphia-style "wooder ice" to confused New Englanders. Then there was the time I told a friend with the flu, "It's too bad you're not at home, where your mom could make you Jello," only to find out he had never heard of eating Jello when sick - a treasured ritual in our family. Puzzling!
