Ingredients
1 tablespoon vegetable oil, such as safflower
2 pounds sweet potatoes, peeled, quartered, and cut into 1-inch pieces
1 cup canned reduced-sodium chicken broth or water
1/2 cup packed brown sugar
2 tablespoons fresh lime juice
Coarse salt and ground pepper
2 tablespoons unsalted butter
1/4 teaspoon cayenne pepper
Preparation
In a large skillet, heat oil over medium-high. Add sweet potatoes; cook, stirring once, until beginning to brown, 2 minutes.
Add broth, packed brown sugar, and fresh lime juice; season with salt and pepper. Bring to a boil; reduce to a simmer, cover, and cook until crisp-tender, 10 minutes. Uncover, and cook over medium-high until sweet potatoes are tender and liquid is syrupy, 7 to 9 minutes more (there should be only a small amount of liquid remaining).
Remove skillet from heat; add butter, and swirl skillet until melted. Season with salt and pepper.
