Candied Walnuts

Vegetable-oil cooking spray (use Silpat if you have one)
1 large egg white
10 oz walnut halves and pieces (about 2.5 cups)
3/4 cup firmly packed light brown sugar

Preheat oven to 325 degrees. Spray the bottom of a rimmed baking sheet with the cooking spray. In a bowl, whisk the egg white until it is completely foamy and no liquid remains. Fold in the walnuts and brown sugar. Toss gently to coat. Arrange the walnuts on the prepared baking sheet, keeping the individual pieces separate. Bake until the egg white-sugar mixture is cooked through and the nuts are golden brown, 12 to 14 minutes. Loosen the nuts from the pan with a spatula. Set aside on a plate to cool.
