This recipe received our Test Kitchens' highest rating. Use a mandoline to cut the potato for the best results; hand-cutting is less likely to produce sufficiently thin and uniform slices. If you have any leftover chips, store them in an airtight container for up to a week. You'll need to bake them for two minutes at 450° to recrisp before eating.
1/3 cup (1 1/2 ounces) finely crumbled blue cheese
Combine first 5 ingredients in a small bowl, stirring well. Cover and chill.
Place potato slices on paper towels; pat dry. Arrange half of potato slices in a single layer on preheated baking sheet coated with cooking spray. Sprinkle with 1/4 teaspoon salt. Bake at 400° for 10 minutes. Turn potato slices over; bake an additional 5 minutes or until golden. Repeat procedure with remaining potatoes and remaining 1/4 teaspoon salt. Serve immediately with blue cheese mixture.
