Buffalo Chili with lime crema, flavored with chipotle and lime flavored sour cream. A delicious riff on a traditional dish. I’m starting off this post with a photo of the Lime Crema. This mixture of sour cream, lime zest and lime juice is key to the uniqueness of this chili. Michele, who originally posted this recipe and judge at the chili cookoff contest noted that she was unimpressed with the stand-alone flavors without this Crema. I agree, it is a fabulous addition.
