Ingredients

4 medium sweet potatoes (about 2 1/2 pounds), scrubbed well

3 tablespoons extra-virgin olive oil

2 teaspoons ground cumin

1 teaspoon hot paprika

1 teaspoon ground ginger

1/4 teaspoon cayenne pepper

Coarse salt and freshly ground white pepper

Lime wedges, for serving

Preparation

Preheat oven to 400 degrees. Slice sweet potatoes in half lengthwise; slice each half into 3 wedges. Place in a medium bowl, and toss with oil, cumin, paprika, ginger, and cayenne pepper. Season with salt and white pepper.

Arrange sweet potatoes in a single layer on a baking sheet. Transfer to oven; roast until potatoes are crisp and golden on the bottom, about 15 minutes. Turn, and continue roasting until golden all over, about 15 minutes more.

Remove from oven; season with salt and pepper. Serve with lime wedges.
