In a deep-fryer or heavy-bottomed pot, heat enough vegetable oil to come halfway up the sides of the pot, to 350 degrees F.

 In a small bowl, whisk together the maple sugar, black pepper, salt, and yellow curry. Reserve.

 Scrub the sweet potatoes clean. Cut in half and then into 12-inch thick wedges. When oil is hot, reduce heat to medium-high and carefully put half of the wedges in the oil. Cook turning occasionally to brown on all sides, about 10 to 12 minutes. Remove to a paper towel lined colander to drain. Sprinkle the fries with some of the reserved spice mixture. Cover with another paper towel to keep warm. Repeat with remaining wedges. via
