6 large baking potatoes, scrubbed (about 3 pound)
Nonstick cooking spray
Preheat oven to 500 degrees F.
Cut potatoes in half lengthwise. Place each half, cut side down, on cutting board and cut lengthwise into 1/4-inch-thick shoestrings. Place slices in a mixing bowl and toss with desired seasoning mixture (see accompanying recipes) or salt and pepper to taste.
Line 2 baking sheets with foil, and coat the foil lightly with nonstick cooking spray. Divide potatoes between the 2 pans and spread evenly. Bake about 10 minutes, remove from oven and turn over the potato slices. Return pans to the oven and bake another 10 to 15 minutes, until potatoes are lightly browned and fork-tender.
In a small bowl combine 2 teaspoons paprika, 1 teaspoon onion powder and 1/2 teaspoon salt. For a spicier mixture, add 1/4 teaspoon cayenne pepper.
In a small bowl, combine 1/4 teaspoon garlic powder, 1/2 teaspoon freshly ground black pepper and 1/2 teaspoon salt. For more zip, double up on the garlic and pepper.
In a small bowl, combine 1 teaspoon chili powder, 1 teaspoon cumin powder and 1/2 teaspoon salt. For more heat, add 1 teaspoon crushed red pepper flakes.
