Inspired by the signature sweetpotato 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 sweetpotatoes in a whole different light. It features whole sweetpotatoes 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.
