I love a dish in which every ingredient matters. The chocolate is extremely subtle but when you notice it, you get a nice surprise. Don't worry—it's not sweet!
We used the base of this recipe to make a veggie chili. It was good, but I was disappointed to not taste the chocolate at all. Also, 3 cans of tomatoes was overkill (and I'm a tomato lover).
I have made this recipe many times for friends and family and everybody says this is the best chili they've ever had, not the best turkey chili, but the best chili period. Highly recommended.
