I went to a cooking demo this morning and the chef mentioned that if you use regular grocery store cinnamon you are using the bad for you cinnamon. I came home and did some research. I remember my aunt saying never use the store cinnamon. I thought she was just picky. I tossed the cinnamon I had and bought the Ceylon. I can't believe the difference in just the smell. Amazing.
