Just like peanut butter, I didn’t realize until I lived outside of the US that cinnamon is another particularly American food/flavor preference.
When I was growing up, I would often sprinkle sugar and cinnamon on my buttered toast. I bake homemade cinnamon buns and I am a regular patron of Cinnabon in shopping mall food courts, lured from afar by the wafting scent of cinnamon.
And of course cinnamon is a key addition to apples, applesauce, apple pie, and any other apple-based dessert, of which Americans are also especially fond. My mother used to make baked apples topped with cinnamon and raisins. We do love our cinnamon.
One thing I have yet to try is peanut butter and cinnamon… but now I’m curious.
