Inspired by the signature sweet potato dish at the acclaimed Cala restaurant in San Francisco, this simple, sublime recipe--created by Carolyn Jung of TheFoodGal.com--will make you look at sweet potatoes in a whole different light. It features whole sweet potatoes buried in ash, and roasted until blackened on the outside, and sweet, smoky and luscious within. The flesh gets spread on warm tortillas with a dollop of creamy chipotle sauce. Sounds amazing, right? Visit Carolyn's site for the recipe.
