4 garlic cloves (smashed, peeled and pressed through a garlic press or finely chopped
3 tablespoons vegetable oil
3 tablespoons olive oil
1 1/2 pounds russet potatoes (about 3 or 4)
2 tablespoons cornstarch
1 1/2 teaspoon kosher salt
Freshly ground black pepper
1/8 teaspoon cayenne pepper (optional)
Method of Preparation:
1. Heat oven to 475 degrees. Quarter the potatoes lengthwise, then cut each quarter further into 2 or 3 skinny, even wedges.
2. Combine the garlic and oil in a large bowl and microwave until the garlic is fragrant, about 1 minute. Pour off most of the oil onto a rimmed baking sheet, and tilt the sheet to coat it; you will leave behind the garlic with around 1 tablespoon of oil in the bowl, and this is just right.
3. Add the potatoes to the bowl and use a rubber spatula to toss and coat them with the oil and garlic. Wrap the bowl tightly in plastic wrap and microwave on high power until the potatoes are translucent around the edges, 3 to 6 minutes, shaking the bowl to redistribute the potatoes halfway through cooking.
4. Combine the cornstarch, salt, pepper, and cayenne in a small bowl. Sprinkle over the hot potatoes and toss well to coat. Arrange the potatoes in a single layer on the prepared baking sheet and bake, turning once, until deep golden brown and crisp, 30 to 40 minutes (I flip them after 15 minutes). Drain briefly on brown paper bags, then serve hot.
