This is my favorite chili. The first time, I made it exactly according to the recipe. Since then, I sometimes alter the hotness depending on who I'm cooking for, but otherwise, I don't make any changes. It has a multitude of flavors: sweet sweet potatoes and tomatoes, tangy lime and cilantro, spicy chili powder, smoky chipotle, and earthy black beans. I haven't met anyone yet who didn't like it, although I did have a few who said, "It's not chili, but it's good!"
(One caveat: My social group are pretty adventurous eaters. They include people who cook medieval recipes like spicy pork and currant pies, so they had experienced and learned to enjoy flavor combinations that are quite unusual in some modern cuisines.)
