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.
