To make the fries: Preheat the oven to 350 degrees F.
Peel the potatoes and cut into desired French-fry size. Place in a plastic bag along with the oil and shake until potatoes are evenly coated. Coat a baking sheet with nonstick spray. Put the potatoes on the baking sheet in a single layer and sprinkle with cayenne and black pepper.
Bake, turning potatoes once, until golden brown, about 20 to 25 minutes.
Meanwhile, to make the ketchup: Stir all ingredients together in a small bowl and set aside. If you like it chunky serve as is. If you don't want the ketchup chunky, put ingredients into a food processor to puree.
When the fries are done, sprinkle with salt and serve immediately with the ketchup.
