Preheat oven to 450 degrees F.
Place the potato wedges in a saucepan with 2 quarts of cold salted water. Bring to a boil and then reduce to a simmer for approximately 5 minutes, or until a knife pierces through easily. Drain. In a large bowl, toss the wedges with olive oil. Place the BBQ spice and salt in a shallow dish and roll the wedges in it. Place the wedges on a sheet pan in single layer and roast for 15 to 20 minutes until crispy.
