Place the 3 cups of walnut halves in a medium-sized bowl
Using a hand mixer, whip the egg white until foamy in a small bowl and add to the walnuts, mixing together well.
Mix together thoroughly the brown sugar, cinnamon, nutmeg, cloves, and cayenne pepper in a small bowl.
Sprinkle the spice mixture over the egg-white coated walnuts and mix well.
Add the orange juice to the walnut-spice mixture and mix together well.
Spread the walnuts on a parchment paper-lined rimmed baking sheet. Bake for 20 minutes. At the halfway point of 10 minutes, using a spatula, flip the walnuts to help toast and crisp up each side for an additional 10 minutes.
Walnuts will be slightly soft when removed from the oven. As they cool on a cooling rack, they will become more crisp.
