Preparation

• Combine all the spice rub ingredients in a small bowl.
• Preheat all burners of a gas grill to medium-high heat or light a charcoal grill.
• Cut the potatoes lengthwise into three-sided wedges. In a medium bowl, toss them with the olive oil, then sprinkle the cut edges with the spice rub (you may not need all of it).
• 如果你使用的是气体烤架,降低燃烧ers to low heat, leaving the other(s) at medium-high to create a hot zone and a cool zone. If you’re using a charcoal grill, bank the hot coals to one side of the grill so that you have a hotter side and a cooler side. (The coals should be 5 to 6 inches from the grate on the hotter side.)
• Put the potatoes on the grill, cut side down, directly over the hottest part of the fire. Cover the grill (if you’re using a charcoal grill, cover it only partially and make sure the bottom vents are open). Cook the potatoes until deep reddish-golden brown, 4 to 6 minutes, and turn them over onto their other cut side. Cover and grill until nicely colored, another 4 to 6 minutes. Move the potatoes to the cooler side of the grill, flipping them so they’re skin side down. Cover and grill until tender when pierced with a sharp knife, about another 6 minutes. Serve immediately.
