We had an office chili cook-off recently (I didn't enter). Two of the chili recipes presented used cinnamon predominately, perhaps even overpoweringly (IMO). Given that they also heavily sweetened their chili with honey and sugar, both had a cinnamon dessert flavor profile mixed with a bland tomato/beef profile. In a word, "yuck!"
In searching today, I've seen several recipes around calling for the use of cinnamon in chili. I could see it maybe being a background flavoring to add a mild spicy bite and a touch of earthiness. But, some recipes seem to be pretty heavy in it's use.
I'm assuming the office cooks didn't develop the right flavor (unless going for a dessert chili was their objective). What kind of flavor profile would be the right one to develop when using cinnamon in chili?
