Adjust an oven rack to the center position and preheat the oven to 350 degrees. Grease a 13 x 9 baking pan. Put the macadamia nuts into a shallow baking dish and toast them in the oven, stirring once or twice, for 5 to 10 minutes or until they are an even, deep golden brown color. Watch them carefully so that they don’t burn. Set aside to cool.
