Cocoa powder adds extra dimension to our chili and enhances the existing flavors. It adds body and a subtle depth of flavor. The bitterness of the cocoa also works to balance the acidity from the tomatoes. What it doesn't do is make your turkey chili taste like a pot of turkey brownies, I promise. While you will get an initial whiff of warm chocolate when you first add it to your pot, the distinct chocolate flavor will dissipate and there will be no lingering chocolate taste.
