1 1/2poundssweet potatoes, scrubbed, skin on, cut into 1" wide wedges
Instructions
Preheat the oven to 425. Put the oil on a rimmed baking sheet that's large enough to hold the sweet potatoes in a single layer. Preheat the pan in the oven about 7-8 minutes, until hot but not smoking.
Whisk the egg whites until stiff. By hand that takes about 4 minutes. If you want to use an electric mixer, allow about 2 minutes.
Stir in the rice flour and seasoned salt, then add the sweet potato wedges and stir gently until coated.
Take the pan out of the oven and put the sweet potatoes on it, turning until each one has a cut side down in contact with the oil. Bake 15 minutes or so, until the sides in contact with the pan are crispy.
Take the pan out of the oven and turn all the wedges until the other cut side is down and bake another 10-15 minutes. Sprinkle more seasoned salt on to taste and serve.
