Ingredients

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

2 tablespoons extra-virgin olive oil

2 teaspoons ground cumin

1 teaspoon hot paprika

1 teaspoon ground ginger

Coarse salt and freshly ground white pepper

Lime wedges, for serving

Yogurt Dipping Sauce for Spicy Sweet Potatoes with Lime, for serving

Preparation

Preheat oven to 400 degrees. Heat a baking sheet in the oven until hot, about 15 minutes. Meanwhile, slice sweet potatoes in half lengthwise; slice each half into 3 wedges. Place in a medium bowl, and toss with oil, cumin, paprika, and ginger. Season with salt and pepper.

When baking sheet is hot, remove from oven. Arrange sweet potatoes in a single layer on sheet. Return to oven; cook until potatoes are crisp and golden on the bottom, about 15 minutes. Turn, and continue cooking until golden all over, about 15 minutes more.

Remove from oven; season with salt and pepper. Serve with limes and sauce.
