Christmas Sugared Walnuts

1 pound of walnut pieces
8 tablespoons of unsalted butter, melted
1/2 cup of confectioners' sugar
1 1/2 teaspoons of ground cinnamon
1/4 teaspoon of ground ginger
1/4 teaspoon of ground allspice
1/8 teaspoon of ground cloves

In a 3 1/2 quart slow cooker, stir the walnuts and butter until
combined. Add the confectioners' sugar, stirring to coat evenly. Cover
and slow cook on HIGH for 15 minutes. Reduce the heat to low, and slow
cook uncovered, stirring occasionally, until the nuts are coated with
a crisp glaze, about 2 hours. Transfer the nuts to a serving bowl. In
a small bowl, combine the cinnamon, ginger, allspice, and cloves. Sift
the spices over the nuts, stirring to coat evenly. Cool the nuts
completely before serving.
