Scrub clean the sweet potatoes using a damp cloth. Slice it lengthwise into thick fries. Soak the fries in a bowl of cool filtered water for half an hour.
Drain, and place the fries on a kitchen towel, pat them dry.
In a large mixing bowl, place the dried fries along with the olive oil and toss to combine.
Next, mix together the corn flour with the black pepper and whatever dry seasonings that you want to use. Add the seasoning mix to the bowl with the fries and toss to coat.
Place the fries on a baking sheet, ensuring that they are spread out evenly across the sheet without overcrowding. Bake until the fries are slightly golden and crispy, rotating the sheets halfway in the middle for even baking.
Remove the fries from the oven, and season with salt while they’re still hot. Toss to combine and wait for a couple of minutes for them to crisp up further. Serve with dipping sauce of your choice!
